Update: A post at the blog Your Genetic Genealogist just went up with a very similar story to mine. Check it out.
It was just a few thin green segments on my fourth and seventh chromosomes that sent me searching. I wanted to know more about my family history. I pestered my mom with questions about her parents, her grandparents and great grandparents. I even went digging on my own into birth records, old newspapers clippings and state archives.
Hidden African Ancestry
Eventually, I wandered into records of our family history on the plains of Nebraska, Iowa and then the hills of West Virginia. I wanted to know what those segments represented – or more accurately – who they represented. I’m white.
My hair, or at least the hair I once had, is blond. (That’s me on the left with my brother when we were kids.) Our family’s heritage is solidly English, Irish and German. I named my son after a Gaelic folk hero.
But those thin green segments in my 23andMe Ancestry Painting meant that one of my grandmother’s great grandmothers, or one of her great grandfathers, was black.
It’s no secret, or it shouldn’t be, that a majority of African Americans have European ancestry — on average between 20 and 25 percent. It’s one of those vestiges of America’s history of slavery.
“For anyone still naive enough to believe in the myth of racial purity, it is one more corroboration that the social categories of ‘white’ and ‘black’ are and always have been more porous than can be imagined,” wrote Harvard Professor Henry Louis “Skip” Gates Jr. in an article in The Root about Michelle Obama’s ancestry.
What Does it Meant to have 1 Percent African Ancestry?
While much has been written about European ancestry among African Americans what’s less well known is how many Americans, like me, who consider themselves white also have African ancestry.
Researchers at 23andMe looked at the genetic ancestry of about 78,000 customers likely to consider themselves as entirely of European ancestry and found that somewhere between 3 percent and 4 percent of those people have “hidden” African ancestry.
The percent of African ancestry is relatively low with the majority of individuals having just 0.5 percent to 0.75 percent – which suggests that those people have an African ancestor who lived about six generations, or about 200 years, ago.
200 Years or Five Generations
This is by no means meant to represent the percent of African ancestry among those who identify themselves as being of European descent across America. It is simply a snapshot of those in our database at this time. Our researchers have also excluded those with more than 5 percent African ancestry with the assumption that it’s more likely that their ancestry is known. That doesn’t mean it is known, just as it doesn’t mean that those of European descent with 5 percent or less African ancestry are unaware of it.
In addition, our database includes customers who are actually European so the actual percentage of Americans of European descent in our database who have African ancestry may be higher. But we believe this is the first detailed look of the African ancestry among those who consider themselves white. It begs many questions for possible future study.
Another View of History
For instance, looking at the generational distribution implied by the percentages it appears most of the mixing occurred 200 years ago or more. Was intermixing between black and white more acceptable during that time in American history? Or was the relative isolation of people then such that the societal taboos against such mixing were more lax?
At the very least these findings suggest a more nuanced picture of race relations at that time. For our family, the news has recast our own picture of who our ancestors were. My sisters and I have 1 percent African ancestry. My mother, a generation closer to the source, has more. For a family that thought we were a mix of Irish, German and French, it was a surprise.
But the surprise triggered our search to find out about our genealogical history. Just as 23andMe’s findings offer a new narrative about American social history and race relations, our family’s discovery offered another look at where we came from.
Somewhere in our family’s past we had a black ancestor who was “absorbed” into white society. That story was hidden until our DNA revealed it. This ancestor would have lived during the era of slavery and at a time and in a place where the “Rule of Hypodescent” – more commonly known as the “one drop rule” – held that anyone with any African ancestry was considered “black.”
Beyond what this might say about American history, the finding also comes at a time when people appear to be much more comfortable with mixed ancestry. So what will this finding mean for other families now? On a personal note, each generation in our family had a different reaction to the news of having an African ancestor.
What’s also interesting is that our evidence of African ancestry, which is very small, can’t be seen in the next generation – the generation of my children and my sisters’ children – who seemed most excited by the new finding and were most disappointed that they didn’t have it.
James Larry Vick, whom we’ve written about before in this blog, talked about his own similar discovery through 23andMe that he had African ancestors. At first he thought it was a mistake, but he has since pieced together the link. He believes it was from his mother’s 2nd great grandmother, who had come from the Cumberland Gap area of Appalachia, home to a tri-racial population known as “Melungeons.” The Melungeons are of European, African and Native American ancestry.
“I do not think anyone in our family would have believed we could have an African segment and none would believe we could have Melungeon ancestry,” Vick said. “I doubt anyone in my family would know what Melungeon is.”
Our own family’s search of records hasn’t led to quite as detailed of a discovery, but it’s offered some tantalizing hints – a “free man of color” with the same surname as my mother’s great grandmother in the same small West Virginia town.
Using 23andMe’s Relative Finder tool I’ve hunted for people with the same surname and family history from that area and this may lead us to new clues. But the journey through this hidden family history has already taught us a lot not just about ourselves but about America’s own hidden history.
