Is there trace Iberian results in your British DNA? This might be why

I’m fast on the genealogy trail of my Welsh ancestors. This involves families like Cadwal(l)ader, Evans, Jones, Matthews, Price and Pugh.

Map showing the geography of the northern part of the Iberian Peninsula with Cornwall and Wales in western and southwestern Britain. 

Looking at my DNA matches for others with these families, I kept seeing trace DNA from the Iberian Peninsula (Spain and Portugal). I made a mental note of this, but it certainly wasn’t anything in the forefront of my mind.

My own Iberian results are minuscule. AncestryDNA doesn’t show it all. Genebase puts it at 0.7%. FamilyTreeDNA estimates it at 0.5%. And various Gedmatch DNA analytic tools puts it between 0.3% to 0.9%. Let’s agree on one thing: it’s tiny. Really, really tiny. I wrote it off as being part of my ancient DNA. It may not be quite as ancient as I assumed.

I’ve come across some interesting articles and books about the genetic composition of the Welsh. Needless to say I learned something new about the Welsh.

I’d always thought that the Welsh were a Celtic people. That’s what I’d heard for the 30 years I’d lived in England. The story goes something like this: the Welsh were the original inhabitants of the British Isles. They were pushed back into present days Wales after a steady stream of invaders: the Anglo Saxons, followed by the Normans. However, there was an even older arrival that had a direct impact on the original Welsh. The Celts.

The first article I came across is an antiquarian piece. And I should caveat this by saying that there is some ethno-centric language and prejudices expressed within it. Long story short, the Anglo-Saxons believed themselves to be superior to the Celtic-Iberian Welsh. This superiority was used to justify their dominance over the Welsh. It’s more than a little racist when it comes to speaking about the Welsh and their Iberian forefathers. Some things never change. Nevertheless, it’s worth reading to gain a basic insight into the geographical movements of older Welsh peoples within Wales as different conquering groups came to occupy their lands: The Athenaeum: Journal of Literature, Science, the Fine Arts, Music and the Drama, Volume 2866:

There’s also The British Quarterly Review, Volumes 55-56:

The last article I’ll reference is a contemporary one: DNA of the nation revealed…and we’re not as ‘British’ as we think (Ancestry.com): https://www.ancestry.com/corporate/international/press-releases/DNA-of-the-nation-revealedand-were-not-as-British-as-we-think

There’s plenty of sound, primary sources that cover this topic. If you’re interested, Google “Iberian settlement of Wales” in either Google or Google Books.

This is one potential explanation for the trace amounts of Iberian in my own DNA. It comes via my Welsh ancestry. Another route will be via my Cornish ancestry, with a slight twist.

The indigenous Cornish are proud of their connection to the Saracens, a Semitic people, who traded goods with the Cornish for much-needed tin.

The town symbol for Penryn, the first Cornish village I lived in? A Saracen. It’s also the logo for the village rugby team, also named for the Saracens.l

The Saracens left more than just goods and currency. They left their DNA among the Cornish too – a source of pride for the indigenous Cornish to this day.

https://books.google.com/books?id=y8c2AQAAMAAJ&dq=saracens%20in%20cornwall&pg=PA55&output=embed
https://books.google.com/books?id=y8c2AQAAMAAJ&pg=PA55&dq=saracens+in+cornwall&hl=en&sa=X&ved=0ahUKEwiXkNbv_7zRAhVGNiYKHc03D04Q6AEIHzAB#v=onepage&q=saracens%20in%20cornwall&f=false

Again, there are plenty of respected primary sources online which provide a history of the Saracens and the Cornish.

I mention this because the Saracen’s trade wasn’t limited to Cornwall or neighbouring Devon. They traded with the Welsh…and the Iberians, introducing their DNA to southwest England and to Wales. The article Genomic signals of migration and continuity in Britain before the Anglo-Saxons (via Nature Communications via http://www.nature.com/articles/ncomms10326) touches on ancient Middle Eastern DNA within the British population.

So why is there only a trace amount of DNA? I have a few hypotheses. I’m doing a fair bit of reading to see how accurate or not this theory is. My Welsh ancestors tended to marry within the same families. Yep – a whole new batch of cousin marriages. These cousin marriages go right back to the 1100’s. Let’s say, for argument’s sake, that half of these ancestors carried small amounts of Iberian DNA. That DNA continued to be passed back and forth, just enough being preserved through 20 or so generations to come down to descendants as trace amounts of Iberian DNA.

9e3940c9542600d489d1482e9643416d

An illustrative example showing how inherited DNA segments become shorter as they are passed down from generation to generation. In this example, let’s say the pink regions in the image above are Saracen. Let the 100% Saracen segment represent a Saracen ancestor.  Working from left to right, let’s say this ancestor married a Welsh Celt (illustrated by the blue). His or her descendants would be 50% Saracen and 50% Celtic Welsh. The Saracen reduces over time within each subsequent generation.

As for the Saracen? This could explain the trace amounts of Middle Eastern DNA results that pop up in my Welsh DNA cousins’ test results. Probably for the same reason as Saracen DNA does. This too requires more reading and research.

Those trace amounts of Iberian is beginning to make sense.

Genetic genealogy, DNA triangulation, and the search for my missing Futrell ancestor

When it comes to my genealogy adventures, more often than not, I feel like Sherlock Holmes or Poirot when it comes to uncovering the identity of missing ancestors who lived in the 17th, 18th and early 19th Century. Paper trails invariably run out, especially when it comes to my ancestors who were either working class whites, blacks, mulattos, Native American, or free people of colour. There are various reasons for this. Either records were lost, destroyed during times of upheaval (i.e. Revolutionary War, Civil War, Bacon’s Rebellion, etc) or were lost due to things like courthouses burning down. Given the remote areas some of ancestors lived, records may have never been produced at all. Or, if enslaved, full names weren’t provided. Or, due to ethnicity, they weren’t seen as people.

DNA testing is one key to uncovering the identities for ancestors where paper documents never existed, or no longer exist…or have yet to be digitized.  The process of DNA triangulation is key to this process:

Triangulation for autosomal DNA is kind of a chicken and egg thing.  The goal is to associate and identify specific DNA segments to specific ancestors.  The easiest way to do this, or to begin the process, is with known relatives.  This gets you started identifying “family segments.”  From that point, you can use the known family segments, along with some common sense tools, to identify other people that are related through those common ancestors.  Through those matches with other people, you can continue to break down your DNA into more and more granular family lines. (DNAeXplained, “Triangulation for Autosomal DNA” via https://dna-explained.com/2013/06/21/triangulation-for-autosomal-dna)

Regular readers will know I’ve developed a talent for triangulation over the years. In truth, much credit goes to my team of genetic genealogists who spent long and patient hours explaining how genetic genealogy and triangulation work; and mentoring me through my first forays into triangulating with my own DNA.

I’ve saved one of the most challenging triangulation tasks for last: discovering the father of my 2x great grandmother, Selinda Futrell, born about 1842 in Rich Square, Northampton County, North Carolina. This falls on my mother’s side of the family tree.

matilda

There are a couple of phases when it comes to organizing how I approach working with DNA and vital documents identifying a parent, or parents, for an ancestor. I’m still very much in the early phases with Selinda.

A preliminary to Phase I

Let’s start with her mother, Melinda, whose name appears as Melinda Futrell in official documents. Melinda was born around 1824 in Northampton County, North Carolina.  The first question I had to tackle was whether or not Melinda was a Futrell by birth, or was it a name she assumed after Emancipation.  In short, what was her connection to the Futrell name?

The three documents I have for Melinda, including the 1870 Census, cite that she is black.  All three documents are consist in this fact. There is nothing to-date to indicate that she was of mixed race. Now this could be for one of two reasons: either she was born of mixed parentage and simply didn’t appear to be.  Or, as I strongly suspect, she wasn’t born of mixed parentage. I am satisfied on the score that she was not a Futrell by birth.

Melinda’s children, on the other hand, are consistently cited as being mulattos. All of them. Which indicates that, unlike Melinda, her children had a white father. Given some 20+ DNA matches with white Futrells and Futrell descendants with roots in Northampton County, North Carolina, the team and I are very confident that man was a Futrell. This would explain Melinda’s adoption of the Futrell name, which she passed on to her children.

This is a prelim into Phase I.

Phase I: The Futrell family tree

So, the preliminary to Phase I was all about determining if Selinda Futrell was indeed a blood relation to the Quaker-descended Futrells in Northampton, NC.

Phase I, which is still ongoing, requires me to do a full and thorough work-up on the Quaker-descended Futrell family tree. This is easier said than done.  I’m not going the lie. The Futrells are a nightmare to research.

Let’s just start with the surname. When it comes to misspellings and variants of the name, it’s in a league of its own: Fewtrell (the old English spelling of the name), Futral, Futrill, Fetral, Tutrill, Titrill, Futrelle…the list goes on and on.

Then there are the beloved family names that were commonly used among numerous branches: Shadrach, William, Charity, Daniel, John, Nathaniel, and Mary, just to cite a few. Online family trees are aren’t an option – too many have confused or merged individuals who borne the same first name and were born within a few years of each other.

The one book I hoped to get a hold of, 12 Northampton County, North Carolina Families
Bridgers, Daughtry, Futrell, Jenkins, Joyner, Lassiter, Martin, Odom, Parker, Stephenson, Sumner, and Woodard by Rebecca L. Dozier is no longer in print.

But then, as luck or providence would have it, I discovered a second book: The Futrell Family Revised by Roger H. Futrell (available to read and/or download via: https://dcms.lds.org/delivery/DeliveryManagerServlet?dps_pid=IE99258)  This book has been an absolute godsend. I’m not exaggerating when I say that we couldn’t have done an accurate family tree without it.

The book allowed us to ramp up Phase I, and begin Phase II.

Phase IIa: Eliminating and shortlisting paternity candidates

The 18th and early 19th Century Futrell family is huge. The family was not only prolific, it produced an unusual number of male children generation after generation.

At the moment, we’re just shy of 60 Futrell men born between 1650 and 1820. In order to have the fullest list of possible paternity candidates, we’re required to try and trace as many descendant lines for Thomas “The Immigrant” Futrell (born 1659 in Shropshire, England, lied for a period in Surry County, Virginia –  and died in 1693 in Bertie County, North Carolina). Once this has been done, we can begin to specifically look at Futrell men who were old enough, and resident in Northampton County, NC prior to Selinda Futrell’s birth in 1842.

I don’t know if ‘luck’ is the right word, but I’m going to use it anyway.  As luck would have it, around two-thirds of the Futrells who were in North Carolina had moved to Trigg and Christian Counties in Kentucky by 1814. Why is this lucky?  These Futrell men are automatically eliminated as possible descendant lines who could have fathered Selinda and her siblings. These Futrells didn’t moved back and forth between Kentucky and North Carolina.  Once they arrived in Kentucky, that was it.

We next looked into the proximity of Futrell men to Melinda and her family in Rich Square.  There were a dozen or so men of the right age either living in Rich Square. Another 8 Futrell men lived within a day’s horse ride away from Rich Square. Then there was the extended family group of Futrells who lived in Onslow County, NC.

Next we looked at which Futrells owned slaves.  This ruled the Onslow County group of Futrells out almost immediately. None of them had enslaved people.

This, again, helps us narrow the field of identifying the best, most likely paternity candidates on paper before we begin using DNA to triangulate.

After eliminating so many Futrells from consideration, we are left with a few family lines to investigate more closely:

  1. Male Futrell descendants of John W Futrell (1715-1788) and Martha “Polly” Daughtry;
  2. Male Futrell descendants of Benjamin Futrell (1720-1790) and Mourning Smith; and
  3. Male Futrell descendants of Thomas Futrell III (1713-1770) and Elizabeth Dickinson.

Work continues in investigating these three family groups.

Phase IIb: Wills and probate…and more Wills and probate

Wills and probate records are a vital – and rich – source of ancestral information. On the one hand, they provide the names of surviving family members, including grandchildren (e.g. I bequeath to my grand-daughter Hezekiah Heathcock, the daughter of Anne,…)

Next, Wills and probate are important for my Futrell ancestry for another reason. Wills and probate tells me who held enslaved people and who did not. This isn’t always a hard and fast rule.  My formerly missing German-American Sheffey 4x grandfather, John Adam Sheffey, was the only 18th Century Sheffey to not own slaves.  However, his brothers did. Yet, as far as DNA is showing, only John Adam Sheffey seems to have fathered children with Jemimah, an enslaved woman in the household of his brother Maj Henry Lawrence Sheffey. Slave ownership isn’t always a reliable factor when it comes to determining paternity.

For the Futrells who held enslaved people, the names of the enslaved are cited in their Wills.  It is actually possible to follow the trail of the enslaved from generation to generation through subsequent Futrell family Wills.

Using an example, let’s say Futrell #1 had an enslaved woman by the name of Amey. She goes from him to his son, Futrell #2.  Next, we might see in Futrell #2’s Will that Amey and her children, Patsy and Shadrach, pass to his son, Futrell #3.  Not only can I track Amey, I can now see that she has two children. Further Wills will provide further clues and information about Patsy and Shadrach.

The above is an illustrative example.  The Will of Elliot Futrell below, is a real-world working example:

elliott-futrell-1elliott-futrell-2

I’ll go ahead and say.  Creating family trees from Wills is a strange and unsettling business. I don’t think I’ll ever reconcile myself to it. With that said, it is a critical skillset to acquire when it comes to genealogy.

As part of my genealogy practice, I add this information my Ancestry.com family tree for the respective individuals who held and inherited enslaved people.  I do this in the hopes that it helps other African Americans  researching their own family trees. I include the names of the enslaved and how that individual came by them (i.e. inheritance or purchase) with links back to the original course. The two images below show my working practice using the Will above:

mitchell-futrell

The image above shows notes I add to respective Ancestry.com pages to track the movement of enslaved ancestors from generation to generation.

Now, in the instance above, I don’t know if any of the enslaved people cited are part of my Futrell family’s story. However, they will be part of someone’s family story. So many have helped me along my way in my adventure, it would be churlish for me to not pay it forward.

Phase IIc: Identifying Futrell DNA segements

While I grapple with the traditional genealogy required in Phases IIa and IIb, the team is working on identifying my Futrell DNA segments and the Chromosome(s) associated with this segment or segments. While I’ve become adept at this part of the process, it is time consuming. And, in this instance, exceedingly tricky due to endogamy (cousin marriages, in short). I’m going to say it: the professionals are far quicker at this than I am!

This article from DNAeXplained gives you a glimpse into what’s involved: Concepts: Match Groups and Triangulation https://dna-explained.com/category/triangulation.

Phase III: Working with online DNA cousin matches

This final phase will do one of two things.  It will either identify the father of Selinda Futrell and her siblings. Or, it will narrow the search down to a single family group, a father and his sons, in other words. Most of the time, we get a solid hit and there’s no doubt about it.  Other times – and this is largely due to endogamy – we can only narrow it down to a father and/or his sons.

For example, it’s not unusual in my family tree for two brothers from one family to marry sisters from another family – and both sets of couples were cousins. Add the fact that the parents of the 2 brothers and 2 sisters were 2nd or 3rd cousins. Nothing skews DNA triangulating quite like this. It’s a bit of a nightmare. Less frequent is a father and a son marrying a mother and a daughter from another family, who may or may not be related to them.

Part of Phase III includes me relaying any possible DNA overlaps back to the genetic genealogists. For instance, the Quaker descended Futrells married Outlands, Exums, Vinsons and Lassiters quite often In Northampton, NC. I know already that I have Lassiters and Exums in Virginia on my father’s side of the family. I also have Outlands from Pennsylvania and Virginia on both my parents’ ancestral lines. Regardless of which colonial territory or State they lived in, these Outlands, Lassiters and Exums are part of the same family. Add in the Quaker White family, which links all of these families and more…and you have some tricky triangulation to do.

This information is crucial for the genetic genealogy team to reduce the risk of them arriving at a false positive. They need to find ‘pure’ lines – lines that don’t share common DNA with any other, in order to successfully identify Selinda Futrell’s father.  We use this as a benchmark against which we compare every other line.

Each Futrell line will be examined individually to see which one matches me closer, in terms of generation, than any other. For instance, if all of my DNA matches are at the 5th, 6th and 7th cousin level, save one that matches me at the 4th generational level or less – the most recent shared match is the one we need to investigate more closely. The identity of her father rests on Futrells who match me more closely in terms of generational distance than any other Futrell descendant line.

Normally, we’d also rely on the length of DNA segments shared, and the number of segments shared, between me and my Futrell DNA matches.  However, because of cousin marriages, I already know we’ll share more DNA in common than is typical for 4th to 8th cousins.  As an example, I have a Quaker cousin in Pennsylvania who Ancestry.com suggests is a 3rd cousin. We know a number of the ways we’re related, which makes us 5th, 6th, and 7th cousins respectively (due to endogamy within the colonial Quaker communities, we share at least 6 sets of common ancestors). We share a crazy amount of DNA segments for two people whose common ancestors lived between 1660 and 1770. It’s not Ancestry.com’s fault, it can only go by what the genetic numbers are telling it.

Yep, I know, it sounds like a whole lot of work to identify one ancestor. It’s what you do when the paper trail runs out.

And why spend so much time and effort to identify a father-owner ancestor?  I’ll touch on that in the next article.

Another paternal brick wall smashed: Margaret Clark(Wythe, Virginia)

Hot on the trail of discovering the most likely paternity for one of my paternal 2x great grandfather, Cornelius White of Wytheville, Wythe County, Virginia…I’ve smashed yet another brick wall for a 2x great grandparent in Wytheville.

Another very length spell of DNA triangulation  has provided a strong indication of the man who fathered Margaret…Randolph Fugate Clark. Like Cornelius White, this result isn’t 100% definitive. Again, it has to do with a high degree of endogamy in the European-descended Clark family line. No. Seriously. First-cousin marriages, two brothers from one family marrying two sisters from another family…and those sisters were their cousins…

This meant that quite a few Clark lines share an unusual amount of common DNA. What clinched it for Randolph, in the end, was the number of DNA segments I share with his descendants, and the length of those segments. Family Wills, which  read to track the movement of slaves within this family, also lead to Randolph being the most likely Clark male to have fathered Margaret.

And then matches like these began popping up on my AncestryDNA account.

Fugate-Clark

Now, the hunt is on to determine the identity of Margaret’s mother, who will be one of 5 women mentioned in relevant Clark family Wills and estate inventories.

Genetic Genealogy & Endogamy: Identifying the father of Cornelius White using DNA Triangulation

The paternity of my 2x great grandfather, Cornelius White, has been a mystery ever since I began my ancestral journey in 2010. All I had was the usual information that could be gleaned from online record sources. He was born about 1829 in Virginia, either in Wythe, Smyth or Augusta County. He married Ann St Clair, who was born in Tennessee. Together, they raised a small family in Wytheville, Wythe County, Virginia.

The only census return I could positively associate with him was the 1880 Census, where he, Ann, and their small family is listed. I had hoped to find him in the 1865 Cohabitation Records for Wythe County. Neither he nor anyone else from his immediate family were listed in this invaluable African American genealogy resource. Nor could I find them in Smyth County, another central location for my extensive extended family. Frustratingly, similar records for Pulaski and Augusta, additional counties that feature largely in my southwest Virginia family’s history, have either been lost, destroyed or undiscovered. So I put Cornelius on the back burner. I’d return to him from time to time – only to put him back on the back burner. I just couldn’t make any headway with him.

I continued my overall genealogy research, on a county-wide level, adding more extended families into my tree. At this point, I have most of late 18th Century to late 19th Century Wythe, Smyth, Pulaski and Augusta county family groups in my tree.

Thanks to endogamy (where groups of people marry amongst themselves, creating one large extended family group over time), I’m related to most of the people in these counties – black, white and Native American – with pre-1900 roots in these counties through a succession of cousin marriages from the early 1700s onwards.

This beautiful region of Virginia is nestled within the Blue Ridge Mountains. It’s sparsely populated even to this day. Before the automobile, it would take a day or more to walk from town to town in this region. So you tended to marry who you knew, which was going to be someone in the same community. Which meant you either married a cousin of some description. Or you didn’t marry at all. I’d imagine that newcomers, who mixed the gene pool up a bit, were feted.  I went through something very similar when I moved to a fairly isolated part of Cornwall in southwest England. I was single at the time and invited to every manner of dinner party, church gathering, local dances, parties and saint festival days you could imagine…with single daughters, grand-daughters and nieces being introduced to me left, right, and centre for the first two years I lived there.

Around 18 months ago, an interesting picture was beginning to emerge where Cornelius was concerned.

Both Cornelius and his wife Ann had something to do with Colonel James Lowry White (1770 – 1838) of Staunton, Virginia. Ann, I believe, was owned by James White. James was the Rockerfeller or Vanderbilt of his day. He was one of the richest men in America with vast business enterprises, land holdings and slaves in Tennessee (Knox County, Ann’s place of birth), Alabama (Huntsville, Madison County), West Virginia and Virginia. For now, Ann’s trail has gone cold. A trip to Tennessee will hopefully reveal more information about her and her immediate family in Tennessee.

Cornelius was a different prospect. I just kept returning to the notion that Cornelius and James were blood relations.  James White fathered one known child by my enslaved 3x grandmother, Elsey George (wife of Jacob Sheffey).  Could he also be the father of Cornelius? I wouldn’t have been surprised. I kept looking at the year Cornelius was born (1829) and the year James was born (1770)…and a father-son relationship just didn’t seem likely. I shouldn’t assume that, I know.  I have distant relations who were still fathering children in their 60s, 70s and 80s. And looking at his family tree below, he was clearly still having children by his wife at the time Cornelius was born.

Could these two men be a grandfather and a grandson? That seemed the most likely prospect. I can’t explain it.  It felt right.

It was time to delve in to the DNA matches I had on Ancesty, FamilyTree DNA and Gedmatch.

Endogamy, endogamy, you will be the end of me!

The first hurdle I was face with was this:  a descendant of the old Quaker White family who had originally settled in Cumberland, Pennsylvania, James Lowry White was already my blood relation 3 different ways:

  1. My mother was a descendant of the same family via her Quaker Harlan lineage;
  2. My father’s maternal Roane ancestors shared common Parke, Dandridge, Henry and Carter ancestors with the James’s maternal Lowry ancestors; and
  3. A marriage between James’s half-sister Margaret and my 5x great uncle, Major Henry Lawrence Sheffey, meant an entire Sheffey line were also shared blood relations between us.

So, in his own right, James was already a cousin twice over – as well as my great uncle. He was also a relation through marriage. Let that one sink in for a minute. That is the joy of endogamy. So, no matter how I looked at it, all of his descendants were going to be my cousins. So how was I going to crack finding Cornelius’s father if James and all of his son were already my cousins?

All of their lines were going to be genetic matches to me.

DNA triangulation was going to be the key

DNA triangulation. So what’s that? In autosomal DNA testing, triangulation is the term used to describe the process of reviewing the pedigree charts of people who match on the same autosomal DNA segment(s) to see if a common ancestor can be found. The technique is best used in conjunction with chromosome mapping. It is a long, long process requiring meticulous attention to detail, care and copious notes.

Triangulation has helped me identify a number of white men who had children – and indeed whole second families- with enslaved as well as free women of colour in my family.

This time around, I knew I couldn’t look at any of the men in James’s tree because they were all already related to me.  I had to look at the women who married them and research their families.

First generation descendants of Colonel James Lowry White of Staunton, Virginia

Looking at the abridged family tree above…there were quite a few sons with wives who required researching.  Triangulation was going to take some time. In this instance…18 months!

The reason why it has taken so long is I had to go back anywhere from 5 to 8 generations for each woman who married into the family in order to be certain that I wasn’t genetically connected to any of them. If I was related to any of these women, triangulation wouldn’t produce the result I needed. In other words, I’d get a false positive as a result.

So let’s start with James Lowry White II’s mother, Ann Marie Lowry.

I wanted to start with Ann Lowry to see if I had any matches on her maternal line. I couldn’t look at her paternal Lowrys. I already knew I shared their DNA.  I had to look at her maternal Boggs line.  As far as I am aware, I only have 1 line of Bloggs.  Sure enough, there they were in my DNA matches: Boggs from her mother’s side of the family. This put all of Ann Lowry’s sons, including James Lowry White, in the frame. The only way I could have a combination of White, Lowry and Boggs matches would be via a son, who would have passed DNA from both parents down to Cornelius, who passed enough of this DNA down to me for me to have strong autosomal DNA matches.

However, just to be certain that I should only be looking at the sons of James, I researched the families of Colonel James White’s sisters in law (James II’s aunts) and came up empty handed. I didn’t share any matches with the names in their trees. Now, that could be because none of their descendants have taken DNA tests – or at least not with AncestryDNA. That’s always an option. Or they haven’t uploaded their results to Gedmatch or FamilyTree DNA. Or not enough of this DNA has been inherited for a positive result.

However, thanks to being active on numerous Virginia genealogy-based Facebook groups, I know of descendants from these allied families who have taken DNA tests. Armed with Gedmatch kit numbers to compare, we quickly confirmed that we didn’t share any DNA. I feel safe to say that while I would be a distant relation to these people via marriage, we are not blood relations. Not through their maternal lines, at any rate.

At this stage, I was confident that I had eliminated Colonel James White’s nephews from the list of paternal candidates for Cornelius.

Next, I began looking at Colonel James White’s sons. One of them would be the strongest candidate to be the father of Cornelius.

I eliminated half of them almost immediately. William Young Conn White I died in infancy, so it wasn’t going to be him.

James Lowry White II was a strong candidate, as were his brothers William Young Conn White II, and Francis Smith White. All of the remaining brothers would have been too young to father a child in 1828/29.  Out of 9 brothers, I had whittled the list of candidates down to 3.

As soon as I began researching James Lowry White II, my heart sank. It was my worst nightmare. His wife, Margaret Rhea Preston, wasn’t just a cousin to me…she was a double cousin. I’m related to her on both her Rhea and her Preston lines.

Undaunted, I continued.

I began working on William Young Conn White II’s wife’s family. It wasn’t long before I hit shared families with her paternal and maternal lines in Pennsylvania, Ireland and Scotland. She was another double cousin. I remember looking out my window and muttering “Are you kidding me?” I was seriously ready to walk away from the whole thing at this point.

I turned to Francis Smith White. He presented another kind of difficulty.  I found very little information about him in the official records or the Virginia genealogy books that form the core of my trusted genealogy research resources. I wasn’t overly dismayed about a lack of results for Francis. Born in 1814, I felt that he to would have been quite young to have fathered a child in 1829. Not unheard of, but quite young nonetheless.

With two White family wives turning out to be my double cousins, I was going to have to tackle this from a different direction. I was going to have to compare degrees of genetic separation between me and the descendants of James White II and his brothers.

I began comparing degrees of estimated relatedness and the amounts and lengths of DNA segments that I shared between the descendants of James II and the descendants of his brothers. My matches are between 1 to 2 generations closer when it comes to James II’s descendants when compared to my matches with his brothers’ descendants.  I share more, and longer, DNA segments with James II’s descendants.

The long and short of it is that James Lowry White II is my prime candidate. However, I have to acknowledge that his brothers William and Francis could also be Cornelius’s father.

I know, it seems an awful amount of work to do to not arrive at a definitive answer.  Sometimes in genealogy – and especially genetic genealogy – there isn’t a clear cut answer.  Not when you have endogamy in just about every corner of your family tree.  All you can do is eliminate the impossible and/or improbable and keep chipping away at the probable until you arrive at what will be the most likely result.

That’s all I can do until a death certificate surfaces for Cornelius. That is, if one exists. If he died before the turn of the 20th Century, there most likely won’t be one. The other possibility is that if a death certificate does exist for him, it won’t necessarily follow that the names of his parents were provided. I could be facing my even older nemesis: ‘parents name unknown’. It’s always worth remembering that such records are only as insightful as the information an informant provided at the time.

At least AncestryDNA offered a kind of consolation prize: 2 shaky leaf hints related to Cornelius. These appeared 48 hours after I placed James White II as his father. One hint shows that James II is a common ancestor between me and another of his descendants. The second showing James II’s father, Colonel James Lowry White, is the shared ancestor between me and one of his daughter’s descendants.

That’s about as good as it’s going to get for now!

This exercise is adding more information about the names freed slaves took after Emancipation. So far, the majority of my formerly enslaved ancestors took the name of their  blood relations. They didn’t just adopt a name they liked. Or pull one from the galactic ether. Which, of course, makes we wonder about the handed down notion that freed slaves chose family names of owners they liked or felt had been kind to them. Or merely because they liked a name. If only a handful of my ancestors had randomly chosen names like that, I wouldn’t give it a second thought. My DNA results are suggesting something fundamentally different.

Interesting too are the minority of my ancestors who could have taken a surname based on a blood connection to a family who owned them – and didn’t. A small percentage of those we’re aware of didn’t simply because they either didn’t like, or didn’t want to be associated with, the paternal European-descended side of their family. Instead, they opted for another kinship-based surname.

It’s an interesting area of research.

DNA.land’s DNA analysis tool’s major improvement

Ok, so I’m known for having picked apart quite a few online DNA analysis tools and services. This is especially true when it comes to my African-related results. So it seems only fair that I share some kudos.

I don’t know what’s been happening over at the Columbia University DNA analysis project, DNA.land…but it looks like the team behind this project have been very busy bees indeed. I, for one, am very, very pleased with the increased accuracy this free service now provides. By and large, it is beginning to reflect the results I received via the paid testing service, Genebase. It’s also substantially more accurate than the results provided by AncestryDNA as far as my African genetic ancestry is concerned.

In its first incarnation, my African genetics were the standard West African and Bantu-speaking. I’m proud of my 8% West African and Bantu speaking genetic heritage (via Genebase). There is a huge difference between being 8% of something and 60% of something.

Now my DNA.land results look like:

dnaland1

The West African results can be more accurate. I know that some of what is being classed as West African here is actually Tuareg and Berber. I’m pretty confident that if DNA.land continues to tweak its datasets, that these parts of my African genome will begin to emerge. At the moment, my guess is that my Berber results are hidden under the Lower Niger Valley category. I suspect that some of my Tuareg results are lost under this heading as well.

However, keeping things positive, ‘East Africa’ finally makes an overdue appearance. 

As for that 1.2% ‘Ambiguous’? That’s where some of my Sephardic Jewish and Middle Eastern results are.

And for my family, let’s not get too excited about the Native American heading. Native American results on any of the DNA analysis services I’ve used remain at 0%. The 1.3% shown here actually represents Amer-Indian genetic matches from Central and South America.  In other words, this has more to do with the pre-historic Eastern nomadic migration into the Americas thousands of years ago.Sorry guys! No Cherokee or Powhatan to be found. This may be due to genetic wash outs…or all those tales amount to myth (Finding Your American Indian tribe Using DNA: https://dna-explained.com/2015/03/31/finding-your-american-indian-tribe-using-dna)

There are a few things to remember when using DNA analysis services and free analytical tools:

  1. Your results will depend on the amount of DNA that the service or tool you’re using has sequenced.  Don’t think that your entire YDNA, mtDNA or autosomal DNA has been sequenced…unless the service you use guarantees this. If you’re paying anything less than thousands of dollars, trust me, only a portion of your genome has been sequenced.
  2. Few DNA testing services are transparent about how much of your genome has been sequenced and analyzed. The more that’s sequenced the better the analysis. It’s a pretty simple equation.
  3. Free DNA analysis tools tend to use free DNA datasets produced by 3rd paties. The quality and accuracy of the data sets used are beyond their control. These data sets are produced by 3rd parties who are not answerable to the services who use them. If this particular topic interests you, you should surf on over to Berkeley’s Drosophilia Genome Project via http://www.fruitfly.org/sequence/human-datasets.html )
  4. DNA anlysis is an evolving science. As more global populations undergo DNA studies (and their results are added to data sets), and as science continues to finesse its understanding of the development and evolution of admixtures, dataset accuracy will continue to improve.
  5. Take early results as an indication of the global cultures you might be connected to. These results will not be definitive. See Point #4.

Keep up the great work, DNA.land!

21 Sep 2016 note: Regular readers will be familiar with my Congo and Central African DNA results, which I should have mentioned here. These too are lumped in under “West Africa” (Why I struggle with ‘West Africa’ as a genetic classificationhttps://genealogyadventures.wordpress.com/2016/03/04/why-i-struggle-with-west-africa-as-a-genetic-classification/). I sometimes forget that it takes time for new readers to read previous dna-related posts on the site

Genetic Genealogy: Parental Phasing Explained

The wonderful DNAeXplained – Genetic Genealogy blog has been posting a series of excellent articles on the topic of genetic genealogy. The one I’m featuring here is on the topic of Parental Phasing using your DNA test results. While it requires plenty of concentration and more than a few steps..it’s an excellent way of working with your DNA test results.

Parental phasing works by comparing your DNA against your matches’ DNA, then comparing your matches’ DNA against your parents’ DNA, and telling you which, if either, or both, parents they match in addition to you.

Oh yes, and there’s one more tiny tidbit – they must match you and your parent(s) on the same segment(s).

denny-me-child

The image above is an example of a Matches Spreadsheet.  Matches are color coded to better see the match comparison relationships. If Denny (a DNA match) matches both me and my child, you will see a common segment on that chromosome for both me and my child in the spreadsheet. Rows where Denny matches my child are light orange and rows where Denny matches me are light blue, similar to the chromosome browser colors.

Mapping my YDNA flow in Africa

I’ve spent the past week and a bit looking more closely at the YDNA I inherited from my father’s male line. It’s like returning to the original genealogical records you use in your research. You come back to them with more knowledge, a more seasoned eye and a better understanding of what you are looking at…and can usually pick up something new.

So, as I learn more about genetic inheritance and develop more finessed  genetic genealogy working practices, I keep returning to my Genebase YDNA and mtDNA results. What I have learn along the way has enabled me to make better sense of my test results. It has also enabled me to make better informed, educated, theories (yes, that is a rather nice way of saying I’m guessing…even if it is an educated guess). And, of course, I’m deeply appreciative of the patience instruction and advice I’ve been given by my genetic genealogy mates.

I’ve made no secret of my love for the Genebase testing service. It was the right DNA tool choice for what I wanted to accomplish. It has been worth every bit of the 4-figure sum I have spent sequencing  and analysing 90% of my YDNA and mtDNA sequence.

I’ve said it before and I’ll say it again. This isn’t a DNA testing service for everyone. There are no quick and easy pie charts that provide ethnic breakdown percentages. You have to work these out for yourself. Sometimes, with this service, you have to work hard in order to interpret the results this service provides. It’s part of what I really like about the service. When you’re forced to work with data of any kind, you have to understand what the data is, how it’s compiled, what it relates to…and ultimately what it means.

The image below gives you an idea of some of the information provided.

Rapanui

Image 1. Click for larger image

I’ll break the information contained in the image above:

This is a small fraction of the data returned by Genebase for my YDNA. The image shows results for a sliver of my YDA: Y-STR markers DYS19a, DYS389i, DYS389ii, DYS390, DYS391, DYS393. By themselves, Y-chromosomal DNA (Y-DNA) short tandem repeat (STR) markers from a Y-DNA test do not have any particular meaning. The value of testing YDNA STR markers comes from creating a YDNA signature (haplotype) with them and comparing that YDNA signature to others in a database. They are useful for genetic genealogy because your YDNA signature distinguishes your paternal lineage from others.

Like any other similar DNA testing service, Genebase compares markers to specific global populations. It groups these results by generational difference (the number of generations you’re likely to be distant from a genetic match). That’s a very over-simplified explanation.  Hopefully, you get the picture.

In the image above, you can see the populations associated with the YDNA STR markers I’ve cited. The report lists matches from a Generational Distance (GD) of 1 to 5.

For transparency, I’m providing a longer abridged list of matches. Trust me, there is a long, long list for these particular markers spread of 6 degrees of genetic distance. That’s a whole lot of cousin action going on:

A partial list of African genetic tribal matches with a GD of 1 and 2.

Image 2. A partial list of African genetic tribal matches with a Genetic Distance of 1, 2 and 3. Click for a larger image.

So back to Image 1 and what it represents:

I’ll get the most obvious one out of the way first – the Rappanui of Easter Island. No, I am not a direct descendant of these people. They are my genetic cousins. Some unknown male ancestor carried my father’s paternal YDNA from Africa (most probably eastern Africa) to Eastern Island. No one knows where the Easter Islander’s ancestors arrived from within the Pacific Region.  That is still hotly debated. However, scientists estimate that humans arrived in Eastern Island around 400CE (Pioneers of Eastern Island http://www.pbs.org/wgbh/nova/ancient/pioneers-of-easter-island.html). Basically, these YDNA markers  that I carry left Africa en route to Easter Island an inconceivably long time ago.

easter island-3

“The middle of nowhere” pretty much sums up Easter Island’s location in the Pacific, marked by the “A” on this map. This beats my paternal grandmother’s mtDNA, which travelled from East Africa to the Aborigines of the Central Australian Desert.

What is pretty cool is the additional information that puts this result into context – something too few DNA testing services do. Genebase lets me know that there were 30 Rappanui tested. I match 2 of those 30 people at a GD of 1. These are my closet matches among the Rappanui. Scoot down to a GD of 2 and the number of Rappanui that share a genetic match with me for these Y-DNA markers jumps to 11 people from the 30 people tested.

Added to this information are research papers, scientific papers that cover the sample pool of DNA testers per region/county, etc. Sometimes, there is additional profile information about the the DNA tester – like which part of a country they resided in at the time they took the test.

For instance, here’s a study that came as part of my Rappanui results: 
Ghiani ME1, Moral P, Mitchell RJ, Hernández M, García-Moro C, Vona G. 2006.
Y-chromosome-Specific STR haplotype data on the Rapanui population (Easter Island)http://www.ncbi.nlm.nih.gov/pubmed/17506287 

Here’s a study on the Omani Arab population:
Alshamali F, Pereira L, Budowle B, Poloni ES, Currat M. 2009. Local population structure in Arabian Peninsula revealed by Y-STR diversity. http://www.ncbi.nlm.nih.gov/pubmed/19339785?ordinalpos=4&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_DefaultReportPanel.Pubmed_RVDocSum

I’d provide a link to one of the African tribes in my match list. There isn’t one.Not in the match results for these markers at any rate.

So…back to Africa.

You can see the African tribes that share the same YDNA markers with me. Like the Rappanui, the greater the GD, the more people I match. When you begin to understand the large scale movements of people across the globe over eons of time, you begin to build a picture of how your YDNA or mtDNA has also travelled around the globe.

Looking at my GD1 results for this set of markers, the information about my African results are the same as my Rappnui results. I have more dataset matches with every increase in Generation Distance. At a GD of 1, I only have a handful of matches. A GD of 2 trebled the number of matching tribes and ethnicities.

Not all of these matches will be direct ancestors. Most, like the Rappanui, will be genetic cousins. Others will be direct ancestors. Given the number of times the Akele, the Puni and the Omani appear in a number of my YDNA markers, my team and I are very confident that I’m directly descended from all 3.

The next step was to build a map to indicate how my YDNA spread through Africa. Again, I’ve only been looking at the African part of my YDNA in this exercise. It’s the part of my identity I know the least about. So it make sense. I have an excellent understanding on the European parts of my YDA. My Near Asian, Middle Eastern, Central Asian, Southern Asian and Chinese results simply defy understanding. They are anybody’s guess at this point. From a personal as well as time and productivity standpoint, it makes sense to focus on the African parts of my YDNA at this point.

A working hypothesis on how my YDNA travelled through Africa

afr_asia_pol2

Let’s start with the blue region on the right hand side of the map. This is the origins of, well, me, in terms of my YDA. It all begins in the Horn of Africa. Like every other human being. At some point in the dim past, my YDNA left Africa and arrived in Yemen and Oman. Now you’d think that it would be found in the Arab populations in both places. Nope. Not a bit of it. In modern day Yemen, it’s only found in the Yemini Jewish population (so far). It’s found within the Arab population of Oman.

At a further point in time, that YDNA returned to Africa. The team is presuming it returned to the eastern part of Africa before heading north to Egypt and then across northern Africa (the pink region on the map). This journey is represented by the arrow marked “1”.

We think my YDNA travelled southeast – shown by arrow 2 – around the time as the same YDNA began making its journey northwards  (arrow 1). This southern journey seems to have stopped in Zambia. At the moment, I have no DNA matches with any of the data sets associated with countries to the south of Zambia on Genebase. Again, this is at the moment of writing this post.

My markers are indicating that something pretty interesting happened after the journeys shown by arrows 1 and 2. My YDNA flowed from northern Africa southwards into the African interior, terminating in Gabon and Zambia (the green and yellow arrows marked by ‘3’). The tribes I match indicate the route this journey took. These tribal cousins can be found in modern day Guinea-Bissau, Burkina-Faso, Ghana, Nigeria, Cameroon and the Democratic Republic of the Congo.

The 4th arrow shows a small journey from Gabon to Angola, home to more genetic cousins (at a GD of 3).

This seems to be as far south as my YDA has travelled within Africa. As science tests and studies the DNA from more African tribes, perhaps a fuller picture will emerge.

For now?  I’m getting a pretty good grounding of the overall picture of my African DNA…and the tribes and cultures it connects me to on that continent.

This is the value of this genetic testing service for me, personally.  I know how much of my DNA sequences have been tested. I have  crucial additional and contextual information about the data sets this service uses and population pool information. I know how many of these testers I match – and the degree of genetic difference between our matches – for all of the markers in the 90% of my genome that I’ve had tested. In some instances, I have general information about their geo-locations.  For what I aim to do, this is all invaluable information. And worth every penny.

The more commercial DNA testing services I’ve used don’t provide this level of information. I have no idea how much of my genome any of the big 3 testers have sequenced. Nor do I know the size of the dataset pools they have used to provide information about indigenous people tested (this is what gives you your ethnicity percentages). Nor do I have any idea how many people I match within those different indigenous data set pools to contextualize the percentages they give.

To be 100% fair, the big 3 commercial DNA testing companies are very upfront about what they do and do not provide when it comes to this level of information. I also don’t mind because I didn’t test with these services to receive this level of information. I used them to do deep work on my family tree via DNA matches on these services. I also use these testing services to meet and work with newly discovered cousins. So they have more than fulfilled their purpose. They too have been worth every penny…just for a very different reason.

It’s worth remembering that DNA testing services are tools. No one tool can do everything. Some are more suitable for certain jobs than others. I’m just grateful that each of them – each in its own way –  has given me more than my money’s worth.

Can we really make assumptions about African American DNA admixtures?

I caught up  with some of the geneticist team who were going to be a part of my first proposed television series the other day. Skype truly is a wondrous thing!  We chatted about my YDNA Haplogroup, E1b1a1a1f1a. There’s something about this haplogroup in particular that has confused me.

To recap for those of you who are new to genetics and genetic genealogy, a haplogroup is a term scientists use to describe individual branches, or closely related groups of branches, on the genetic family tree for human beings. In theory, all members of a YDNA haplogroup (passed from fathers to sons) can trace their ancestry back to a single individual until we reach a theoretical genetic ‘Adam’, the father of every male on the planet. Women have a genetic ‘Eve’, the point of origin for human mtDNA (passed from mothers to daughters).

So, we had a chat about good ole E1b1a1a1f1a. In order to have an informed discussion, I gave them access to my Genebase account. Genebase is the DNA testing company I used to test the full sequence of my YDA. It’s worth noting that other, more commercial, DNA testing companies test only various parts of YDNA and mtDNA.  I needed full sequencing done as a basis for my TV series.

Let’s take a quick look at the information they needed which formed the basis of our discussion. To be 100% transparent, we stripped out all non-African DNA from the results. I only wanted to look at the African part of my YDNA, which was the bit that was causing me all kinds of confusion.

My YDNA sequencing:

Image of a partial snapshot of my YDNA sequencing results.

This is a partial snapshot of my YDNA sequencing results from Genebase, with various genetic mutations marked. Click for larger image

At this point, Tim, one of the geneticists (and he also happens to be an anthropologist) said that he saw something interesting – something he hadn’t noticed before when we were planning the TV series. But he wanted to wait a bit until he mentioned what it was. He wanted to see if the other two people on the Skype session would notice the same thing.

Before we went there, we looked at the cultures and tribes I’m genetically linked to via my YDNA.  You can see this in the two images below:

African tribes my YDNA links me to based on my DYS19a, DYS389i DYS389ii DYS390X DYS391 DYS393 YDNA markers

African tribes my YDNA links me to based on my DYS19a, DYS389i DYS389ii DYS390X DYS391 DYS393 YDNA markers. You can also see some of the tribes and cultures I’m genetically linked to at genetic distance of 2. Click for larger image

Image showing my DYS385a, DYS385, DYS392, DYS393, DYS456, GATAH4 marker results. Click for larger image

You’ll notice a neat little phrase in the the images above. It’s Genetic Difference. “Genetic distance” is the number of mutation “steps” or mismatches between any two individuals.  “0” is a perfect match, “1” is a one-step mutation, etc.  The more mutations, the longer the probable time period since the most recent common ancestor.

So, based on the last two images above, I am closely matched with the Akele and the Punu in Gabon as well as the people of Oman. I’m also closely matched with Egyptians. The second image is unusual in that it (currently) connects me to Egyptians and no other culture or tribe.

Let’s look at where the Akele and Punu are found in modern Gabon:

Ethnographic map of modern Gabon. Bakele=Akele and Bapouno+Punu

Ethnographic map of modern Gabon. Bakele=Akele and Bapouno+Punu. Click for larger image

The Punu (also referred to as Bapunu and Bapounou, are a Bantu speaking group from Central Africa.  It’s one of the four major peoples of Gabon, inhabiting interior mountain and grassland areas in the southwest of the country, around the upper N’Gounié and Nyanga Rivers. Bapunu also live in parts of the Republic of the Congo. Punu traditions record a migration from the south sometime before the 19th century, as a result of wars somewhere between the Congo and Niari River.

The Kele people (also referred to as Akele, Bakele, Dikele, and Western Kele) are also an ethnic group in Gabon.

Realization #1

Now the 3 chaps I was chatting with took one look at my Haplogroup and responded along the lines of “ok. African Haplogroup. It get’s lots of traction in Central Africa, particularly in and around the Congo region.”

That’s when I asked them to look at the people I’m linked to (Akele, Punu, Omani and Egyptian).

This is the point when Charlie and Rob chimed in, almost in unison. “Whoa, wait a minute, E1b1a1a1f1a is really rare in Gabon. This doesn’t make any sense”. I laughed at this point and welcomed them to my world of confusion.

It turns out that E1b1a1a1f1a is rife with confusion (oh lucky me!). This Haplogroup is a fairly recent classification. As more human populations undergo DNA testing, the more we understand about YDNA, mtDNA and the haplogroups they have been assigned. Which is a good thing. It’s worth remembering that Genetic genealogy and commercial DNA testing are still in their relative infancy. Further research and testing means a more refined understanding of genetic inheritance. It means a more finessed understanding of us – human beings. What’s known and understood now will undergo refinement down the road. We’re at the tip of the iceberg in terms of understanding the human evolutionary history. There is so much more yet to be uncovered, much less understood. It’s worth remembering that too.

I say this to highlight the point that there is only a basic understanding of the E1b1a1a1f1a haplogroup. E1b1a1a1f1a is linked to western Central Africa. It is rarely found in the most western portions of West Africa. It is, however, prevalent in Nigeria and parts of Gabon (The Bantu expansion revisited a new analysis of Y chromosome variation in Central Western Africa. https://dx.doi.org/10.1111%2Fj.1365-294X.2011.05130.x). It’s also closely linked to eastern and southeastern Africa (Eritrea, Somalia, etc), where one group of geneticists believe it originated. There is another genetic school of thought that states that E1b1a1a1f1a’s origins are Levantine (basically, the Eastern Mediterranean, the Arabian Peninsula and Egypt).

If the scientists can’t agree, what’s a poor genetic genealogy adventurer to do?

So this is where Tim chimed in. He’s the one who noticed something unusual in my YDNA sequence:  “Anyone else notice the DYS391P mutation?”

outline1

My partial YDNA sequence with the specific mutation the geneticists were discussing.

The other two men’s reactions were priceless. Charlie: “What, what?, back up a minute”.  Rob: “Yeah, we need to back up for a sec. How did that happen?”

At this point I laughed and just said “You tell me, you’re the scientists”.

Direct ancestors & genetic cousins

africa_asia.eps

A map of Africa and the Arabian Peninsula. The blue areas are the ones I cite in this post. The pink areas are also in other parts of my YDNA sequencing at a genetic distance of 1. As you’ll see, Gabon is notable by its geographic distance from everywhere else I have a genetic link to at a genetic distance of 1…which raises the fundamental question: How did that happen? Click for a larger image.

Rob and Tim got into an interesting conversation about my haplogroup and the very specific mutation within it. Both made a good point. I’m genetically connected to a staggering number of African tribes. Rob and Tim pointed out that I will be a direct descendant of only a few. All of the others would be genetic cousins. At a mutational difference of 1, the Akele, the Punu, and the Omani are the best candidates for being my direct ancestors. The Egyptians are too. They are just an older direct ancestor pool. At the moment, we’re speculating that all of the other tribes and cultures with a genetic distance greater than 1 would be genetic cousins. In other worlds, I’m not a direct descendant of them. We share a common ancestry further back in time. That time frame could be a few generations (prior to my unknown ancestor’s enslavement and transportation to the United States) for some, to centuries for others…to millennia.

All 3 surmise that at some point within the last 1,500 years or so, an east African man, with Arab male ancestors, carried my YDNA, with a key mutation, into north Africa and northwest Africa. This tallies with the other cultures and tribes in my YDNA, namely the Berber and the Tuareg. At some point, one of his male descendants, a Berber-Tuareg man with this haplogroup and DNA, settled in what’s now present day Gabon.

That’s not surprising. Africa has truly ancient trade routes. And where there are trade routes, there are people. Where there are people, DNA gets exchanged and admixtures arise. The following scientific paper, suggested by Charlie, made for some insightful reading into this specific subject: Sacko, O. Influences of Trans-Saharan Trade’s Cultural Exchanges on Architecture: Learning from Historical Cities and Cultural Heritages in Mali and Mauritania ( http://www.kyoto-seika.ac.jp/researchlab/wp/wp-content/uploads/kiyo/pdf-data/no39/oussouby_sacko.pdf)

To shed some light on this, you’ll find some images that show ancient African trade routes.

East Africa trade routes:

Once established among either the Akele or the Punu, this ancestor’s male descendants married and produced offspring who melted into the surrounding tribal landscape. At some point, one of his male descendants was enslaved and sent to America. That’s the theory my 3 colleagues presented in the end. Much more DNA testing needs to be done on African populations to better understand the evolution of present day African admixtures and history. Significantly more DNA testing needs to be done.  I offer this exchange:

So what’s common and what’s not when it comes to African  Admixtures?

Charlie: “Brian’s haplogroup and this mutation just aren’t commonly seen in Gabon.”

Tim: “How do we know that? Science has barely scratched the surface when it comes to African DNA. We just don’t know. I don’t. Maybe it is rare. Maybe it isn’t. We just aren’t in a position to say what is or isn’t common with African DNA. What I will say is that I find this very, very interesting. It’s something I want to spend some time looking into.”

Charlie offered an interesting and plausible insight. He suggested that perhaps the ancestor who was abducted and then sold into slavery was specifically chosen because it was known that his family wasn’t indigenous to Gabon. They may have been part of the Akele and Punu for only a few generations. If his family had a falling out with a rival family or clan, that’s all it would take. The Akele and the Punu were both heavily engaged in the Atlantic slave trade. So they had the means and the connections to abduct and then sell a perceived ‘other’. Considering what’s happening all around the globe right now, this scenario isn’t just conceivable, it is highly probable.

When it comes to African American ancestry, what’s ‘normal’

Rob asked an interesting question: “Do you guys think Brian’s sequencing is common or uncommon in African Americans?”

I beat them all to the punch with a simple question: “What’s considered ‘common’ when it comes to African American admixtures?”  I was asked to clarify the question, which I duly did. I pointed out these numbers from the last US Census:

1) 45,672,250 or 14.3%: Black Only or Black in combination with another race;

2) 42,158,238 or 13.2%: Black Only;

3) 42,316,387 or 13.3%: ‘Black Only’ or ‘Black in combination with another race’ (non-Hispanic); and

4) 39,528,225 or 12.4%: Black Only (non-Hispanic)

This doesn’t cover those who self-identify as black and Hispanic, etc – or those who don’t even know that they have an African descended ancestor.

It’s believed that 1 million Americans have taken DNA tests. I haven’t found any reliable statistics that show how many of these DNA test takers are African descended Americans. I suspect that the number of African Americans who have taken DNA tests is a very small percentage of that overall 1 million figure. Infinitesimally small. Statistically speaking, not large enough to make any qualified statements.

This happens to be a huge bugbear for me. There are shows that make assertions like: most African Americans don’t have Native American ancestry, or, if they do, that African Americans ‘usually’ have X amount. Or, that few African Americans are 100% African in their ancestry. Or, that any given African American will have Y% of European ancestry or SE Asian ancestry… the assertions go on and on. If this subject interests you, Tim recommended an excellent article: The Genetic Structure and History of Africans and African Americans (http://materiais.dbio.uevora.pt/MA/Artigos/Genetic_Structure_and_History_of_Africans_and_African_Americans.pdf)

Now, if 10 million African Americans were to take DNA tests, then we’d have a significant DNA data set to begin making generalized DNA-based statements. Today? We’re working in a dark room without any windows or light. Just a single candle. That’s just not enough illumination to make any kind of definitive statement. Sorry, but I am stickler for such things.

The same is true of African DNA. We just don’t know if the prevalence of any given genetic admixture is typical or atypical. We know more about how DNA travelled from eastern Africa to China than we do about how it travelled from eastern Africa to all other points in the African continent. The remoteness of some tribes is a barrier to large scale genetic testing. Then, there’s the climate: arid and acidic soil conditions – as well as extremely moist environmental conditions – which aren’t conducive to preserving human remains, much less fragile DNA. Such finds would enable science to study the ancient roots and migrations across Africa of the ancient peoples who gave rise to the modern day tribes we see today. Then there’s the question of where to look for ancient remains to test, and then compare to modern day tribes. Africa is a huge continent. Looking for this is like looking for a needle in one huge haystack. Science has some real barriers when it comes to the genetic testing of African populations.

I was pretty pleased when all 3 men agreed that there is a need to stop asserting what’s typical when it comes to the DNA of African descended people.

Tim asked my opinion about whether or not I believed that the vast majority of American slaves came from western Africa. I didn’t hold back. Given the number of slave ports on the western African coast, one could assume that a significant proportion of slaves sent to the United States probably did come from the western African coastal region. What that number would actually be is just a guess.

And me being me, I went one step further with one of my analogies: New York City is an enormous port. Every manner of products and goods are shipped from, or flown out of, New York City. It is one of America’s exporting hearts. Not every single product or goods shipped out of New York came from New York or was produced in New York. They come from all four corners of the United States. It would take close inspection of export documentation to determine what percentage of good shipped from New York City actually came from New York, or the surrounding Mid-Atlantic or New England states.  One could assume what percentage of these came from this region. Maybe you’d be right. Maybe not. Only research could reveal what’s correct and what isn’t.

The same holds true for African American genetic genealogy as well as African genetic studies. For the time being, I don’t think anyone really knows. This needs to be understood and accepted. We just don’t know. I appreciate that’s a hard thing to hear. I say this to myself each and every day to manage my own expectations.Enslaved African ancestors could have come from pretty much anywhere in the African continent.

For the time being, I take my genetic results as an indication. No more and no less. My YDNA test indicates that I’m a direct descendant of an African man with an interesting Arabian Peninsula-East African-North African-Akele-Punu admixture. How he got that admixture is anybody’s guess. When that admixture occurred is anybody’s guess. And as more African people have their DNA tested and studied, this picture will hopefully become more finessed. Hopefully, the missing puzzle pieces will fall into place.

My geneticist friends are troopers. Bless them, I’ve hit them with a barrage of questions. None of the questions I’ve asked are easy to answer. Thankfully, they find them really intriguing questions that have piqued their interest.  I ask questions because I want to know. *smiling* and I can’t begin to tell you how badly I want to know. Are the Yoruba my first or second cousins, genetically speaking? Are the Fulani my second cousins or third cousins twice removed? Are the Baka something like a 10th great grand uncle?

I want to tackle this basic and fundamental set of questions before I even begin to think about how I’m genetically linked to everyone else in my YDNA – Central Asian, Persian, Sephardic Jewish, SE Asian, Korean and European.

To do the kind of genetic genealogy adventure TV series that my heart of hearts wants to do – we definitely need to figure out this smorgasbord of YDNA.

There’s a practical reason for wanting to know. I share my finds with my wider family, who find all of this fascinating (to various degrees). When you tell your family members you’ve found a new cousin, the first question is usually a simple one: how are we related? In straightforward genealogy, you can show them a family tree and walk them through the connection so they can see it for themselves.

I’d love to be in a position to do this with the global tribes and cultures we’re linked to. That’s the one thing I can’t do at the moment. And yes, I want to know for me. *grinning* For once, I can make this all about me. I want to know. I want to know where these different global groups of people fall on my YDNA tree.

Mapping my father’s mtDNA to African tribes

It probably comes as no surprise that I’m a conceptual thinker. And few things aid my understanding of concepts better than visuals. Especially when I create visual materials. As I create things I begin to see inter-relationships in a tangible way. It’s the way my mind rolls, and I’ve learned to embrace it.

It’s like baking a cake. Ok, I get what a cake is. However, when I combine the different ingredients, and know their individual properties and how they interact with each another, I get how a cake is actually made. You don’t see the egg or the butter or the milk in the final product, but you know they’re there and how they contributed to the overall cake.

With this in mind, I’ve been making maps of the African tribes my father and I are descended from.

I’ve made 3 maps that cover:

  1. My Y-DNA (haplogroup subclade  E1b1a1a1f1a1) – the DNA that is passed down from fathers to sonsdna-reunion-y
  2. My mtDNA (haplogroup subclade L2a1c4a) – the DNA that is passed down from mothers to daughters. Mothers also pass this on to their sons. Sons, however, do not pass this on to their children.dna-reunion-m
  3. My father’s mtDNA (Haplogroup L3). I am so grateful that he took this test. He is the only living link I directly had to his mother’s mtDNA.dna-reunion-m

This project helped me to better understand:

  1. How each of these 3 sets of African DNA travelled within the African Continent; and
  2. Which tribes I’m directly descended from, and which tribes are genetic cousins.

The second point will have a role to play when the time comes to start pinpointing specific African ancestors who were captured and sent to the American colonies as slaves. In other words, it saves me from trying to look for a needle in a haystack. Instead, I can look for that needed in a specific part of the haystack.

Some interesting possibilities revealed

MY Y-DNA and the 2 mtDNA tests were done via Genebase and form the basis of this mapping project.

My Y-DNA and mtDNA tests connect me to a staggering number of African tribes. Thinking logically, I knew I couldn’t be a direct descendant of all of them. As I mentioned above, only a handful were going to be the tribes of my direct ancestors. All of the others would be like second or third cousins, etc.

It turns out that once I made a map, some interesting possibilities presented themselves. I’m going to do an individual post for each of the 3 maps. It makes it easier to convey the story each map is beginning to reveal.

My father’ maternal mtDNA mapping results

I’m going to start with my father’s maternal mtDNA, the mtDNA he inherited from his mother, Susan Julia Roane (remember, I didn’t inherit any of this mtDNA):

Susan Roane mtDNA outlined

Plotting the direct female mtDNA African lineage of my grandmother, Susan Roane. This map illustrates how her mtDNA was carried from east to west within Africa (Organe-brown arrow). The blue and green arrows show how this mtDNA was carried into southern Africa through her female DNA cousins. Click for larger image.

 

A few things to keep in mind before I delve into how I’ve interpreted this map:

  1. The number of African tribes that have been tested is relatively small compared to non-African populations; and
  2. For the tribes that have had their DNA tested and sequenced, the number of people tested can be quite small (like the 27 Somalians who were tested and whose results from part of Genebase’s research and indigenous peoples’ results).

So what does this map tell me?

Well, like every human being on the plant, the journey begins in the Horn of Africa. So no surprises there.

Susan Roane’s direct maternal ancestor’s DNA travelled into the heart of the African continent. I’ve illustrated this with the big orange-brown arrow. Her ancient female cousins (e.g. not her direct ancestral line), carried the same mtDNA into southern Africa – both along the east and west coasts.

Her direct, African female ancestors appear to have settled in and around the Greater Lake Chad region, including northern Cameroon. You can see this in the cluster of tribes formed by the Fali, Fulbe, Kanuri, Kotoko, Mafa and Masa.

I’m thinking that the Fulbe in Niger, Nigeria, Mali and Senegal are genetic Fulbe cousin lines. Too much of her mtDNA is clustered in northwest Cameroon and southwestern Chad. It’s here that I think the woman who was the mother of Susan Roane’s American female line came from. My father shares only a small number of mtDNA markers with the Fulbe outside of this Lake Chad zone.  His strongest Fulbe mtDNA results specifically point to Lake Chad and its environs.

So what’s the story with the Fulbe?

I’m doing quite a bit of research on these tribes. However, an interesting picture has begun to emerge.

While they are rarely discussed, Africa had ancient kingdoms. The central African kingdom that encompassed my grandmother’s mtDNA was the Fulani Empire. You can see this empire in the picture below:

fulani-presence-in-west-africa

Fulani Empire in western  Africa

There’s quite a bit of Fulbe in my grandmother’s mtDNA. The Fulbe were part of the Fulani tribe. It turns out that the Fulani have quite the history.

The Fulani are an ancient tribe. By ‘ancient’ I mean the ancient Greeks (Herodotus, to be specific), Egyptians and Assyrians wrote about them. I’m finding it difficult to get a handle about the origins of the Fulani. There’s quite a bit of positive and negative propaganda about them. Depending on the author, there’s a vested interest in saying that the Fulani either came from this place, or that place or some other place. So I’m taking what I’ve read so far with a pinch of salt. I’m still searching for a respected, credible source with verifiable information.

Some sources say they came from India. Others claim they came from northern Africa. Yet others claim the Fulani came from eastern Africa. There is one point pretty much all the authors I’ve read so far agree on: the Fulani were not indigenous to the Lake Chad and western African region.  Anthropology has shown that this region had been previously settled by tribes with a far older history in the region.

There are claims that the Fulani introduced Islam to Africa. I don’t know if this is true or not. I do believe, however, they were early adopters of the Islamic faith. In turn, they made it the official religion of their empire. You can read a bit about the Fulani and Islam here: The Spread of Islam in West Africa: Containment, Mixing, and Reform from the Eighth to the Twentieth Century,  http://spice.fsi.stanford.edu/docs/the_spread_of_islam_in_west_africa_containment_mixing_and_reform_from_the_eighth_to_the_twentieth_century

The other tribes I’ve pinpointed in the Fulani-controlled area in map above were also largely Muslim. Like other Fulani-related tribes, they were active traders and I can easily imagine marriages between them. Which would explain their genetic markers in my paternal grandmother’s mtDNA.

The Fulani were also slavers. Large scale slavers – selling Africans into slavery within Africa and to Europeans. This is covered in the Wikipedia article below.

Some articles about the Fulani:

  1. Wikipedia (It’s Wikipedia – so by no means a definitive authority on the subject):  https://en.wikipedia.org/wiki/Fula_people#Timeline_of_Fulani_history
  2. Who are the Fulani People & Their Origins:  https://tariganter.wordpress.com/2011/09/17/who-are-the-fulani-people-their-origins/

Back to the Fulbe

The Fulbe were also largely Muslim. They had the designation of being free men within the Fulani. I need to do a lot more reading about this to understand what that term actually meant. I’m wondering if the Fulani had a caste system with various designations between free men and slaves. I’m definitely curious. I’m curious because I’m willing to bet, based on the map I’ve created, that my paternal grandmother’s enslaved mtDNA ancestor was Fulbe. And, if she was Fulbe, she would have been a free woman within this society. In all likelihood she would have also been Muslim. So how did her story end as a slave in the American colonies (presumably colonial Virginia)?

Looking at my father’s mtDNA connections in America, 85% are at an 8th generation level. That means the common female ancestor he shares with them lived centuries ago. Generational computation is a tricky thing. Lifespans vary from century to century and from region to region. Nor do I have any idea what the average lifespan of an African slave in America was. It’s always worth remembering this.

This being said, at an 8th generation level, I’m going to take an educated guess that the female Fulbe ancestor he shares with this 85% would have arrived in America sometime between the 1680s and the 1710s.

Genealogy – you get some definitive and probable answers…and a bunch of new questions.

The answer that’s emerging from this map project is that one of the ancestors who made that voyage from Africa to the American colonies was a woman from the Fulbe people. While this doesn’t tell me her name, or exactly when she was abducted and sold, it narrows my search. For instance, I can narrow down the number of African ports from which Fulbes were shipped to America between 1680 and 1720. From there, I can gather a list of slave ships that left western African slave ports for Virginia. And from there, I can see if any have Fulbe women were listed.
