ABOVE: Slave row

A 200-year-old broken pipe pulled from the ground of an old Maryland plantation holds the DNA of an enslaved woman who was probably related to a specific group of people living in what is now modern-day Sierra Leone, researchers reported March 11 in the Journal of Archaeological Science.

This is possibly the first time an artifact links an American slave with his or her origins in an African people group, according to The Washington Post

“In this particular context, and from that time period, I think it’s a first,” paper coauthor Hannes Schroeder of the University of Copenhagen tells the Post. “[I]t’s exciting for descendant communities . . . Through this technology, they’re able to make a connection not only to the site but potentially back to Africa,” he says.

Because DNA degrades over time, scientists were skeptical about whether they could recover enough DNA from pipe stems found at the site to analyze. But upon extracting the DNA from this one stem, they learned that it belonged to a female and was likely linked to the Mende people of what is now the West African country of Sierra Leone. 

“As soon as people stepped on those slave ships in Africa . . . whether they were from Benin or whether they were from Sierra Leone, wherever they were from, that identity was . . . lost,” Schablitsky tells the Post. The finding sheds light on the woman’s origin and ancestral community, though it’s unclear whether she or her parents were from what is now Sierra Leone.

The authors note that analyses of ancient DNA like this one may also help living descendants find their connections to these places.
