For African Americans, DNA Tests Reveal Just A Small Part Of A Complicated Ancestry

An illustration of African Americans questioning their origins.

Many African Americans don't know where their ancestors are from due to the transatlantic slave trade. They're increasingly using DNA test kits, like those manufactured by 23andMe, but aren't finding complete answers.

It took nearly 30 minutes for Eric Depradine to extract a saliva sample from his dying grandmother.

Depradine, 35, of Kansas City, wanted to have his grandmother’s DNA tested to confirm his suspicions that her ancestors came from Madagascar. He’d read author Michael Twitty describe in "The Cooking Gene" how African Americans who lived in eastern North Carolina — like Depradine’s paternal grandmother — very likely descended from Malagasy people, an ethnic group in Madagascar.

African Americans often have scant knowledge about where their ancestors are from, so many are using DNA test kits, like 23andMe and Ancestry, to trace their roots. The transatlantic slave trade erased a lot of information about family history and countries of origin for many people descended from African slaves.

“There’s no value you can put on a DNA test when you’re researching your family history as an African American,” said Crystal Williams, an East St. Louis resident.

“They tell you can get so far, but that’s not true,” said Williams, 49. “Along with DNA and all the documents that are coming to light. You can go past slavery.”

The results alone don’t provide a complete answer, Depradine said.

“It’s wonderful to get your results. [23andMe] has this great pie chart, and you may be related to a thousand people,” he said. “But it’s no substitute for paper research.”

A DNA Test Can Kick Off A Search ... But Won't Give All The Answers

Kathleen Brandt, a professional genealogist and private investigator based in Kansas City, sees many African American clients who are seeking information about their ancestral origins. She advises all of her clients to have their DNA tested.

“DNA is a tool to use for our family history,” Brandt said. “It is not the answer but gives us right direction where we need to be researching.”

When paired with records containing information about slave owners and emancipation, DNA tests can help kickstart a search that has helped her find out which ship or slave port was involved in transporting a person’s ancestors to the Americas, Brandt said. It’s an essential tool, especially since enslaved people often changed names, which can make research difficult.

Some, who had surnames that were the same as the plantation owner’s, changed their names when they began working at a different plantation. They may have also called themselves something different when they became emancipated, she said.

Some DNA tests are also limited in how far back in time they can reach. That’s why FamilyTreeDNA is more preferred than Ancestry and 23andMe, which can only go back five generations, Brandt said. 


“Ancestry only helps us a little bit,” Brandt said. “In my family, I have traced to the 1700s, a slave side and a free colored side. We were already in America of course, so that pretty much takes care of those five generations those tests are good for. So I have to go to a more comprehensive test that gives me more years that I can work with.”

The tests don’t always give a definite answer when it comes to ethnicity. As more people submit their genetic materials to DNA test kit companies, the results can change. Brandt warns her clients not to become too emotionally invested in their results.

“There’s nothing worse than people getting attached,” Brandt said. “Because it’s hard to explain, ‘I’m so sorry you’re not a 100% Scottish, Irish or Cameroon. It’s a difficult process, because [there’s] a lot of stake in our identity.”

It's Hard Not To Get Emotionally Invested

When people ask Aliah Holman where she’s from, she answers, “St. Louis.” She said she never thought much about her answer until she attended college in New York and met classmates from African countries who were unsatisfied with “St. Louis.”

“They were looking for a more cultural answer and not the geographic answer,” she said. “That was almost a little hurtful. So they wanted to dig a little deeper, and they’d ask more questions, like, ‘Where are your parents from? I’d say, 'My mom is from Arkansas,' and I could see the disappointment in their eyes, because that definitely goes straight to a narrative of, ‘Oh yeah, you’re definitely a slave American.’”

Yasmira Emofor, also of St. Louis, experienced similarly tense moments with Africans.

“Most black Americans assume Africans know about the slave trade,” Emofor said. “That, I think, is a fallacy.”

Nigerian people in particular would insist that Emofor was Nigerian.

“Nigerians would say, ‘It’s how you carry yourself. It’s because you’re thin,’” she said. “That didn’t make a lot of sense to me. There’s a lot of thin black people.”

Yasmira Emofor of St. Louis said a lot of Nigerians would approach her and say that she must be Nigerian because of her appearance.

A test from ConnectMyDNA confirmed that Emofor was of Nigerian, Bahamian and French ancestry. When people ask where Emofor’s from, she responds with St. Louis, “but I took a DNA test, and it said I was probably Nigerian.”

Holman’s search was more complicated. While her geographic knowledge of her mother’s family line stops at Arkansas, she knows her father’s parents came from Jamaica. But the country is more a part of her national identity than an ethnic one, she said.

“I think we all still understand there is some part of the diaspora involved where the Jamaicans were brought over from one of the countries on continental Africa,” Holman said.

A more recent and major reason that motivated Holman to buy kits from Ancestry for her parents were aggressive remarks people would make to her when she’d comment on politics.

“I’ve been told, ‘If you don’t like it here, well, go back to Africa,’” Holman said. “But where can I go back to? There is no ‘back’ for me. My home is here, and I don’t even know if I would be accepted ‘there’ or be welcome.”

Aliah Holman of St. Louis had her parents' DNA tested so that she could find out where she was from because of the comments she received from Africans and other people.

When her father’s test results arrived, it showed that the country with the largest percentage was Nigeria, about 40 percent. However, she logged into his account a year later and found that the percentage for Nigeria dropped to about 3 percent, and that Cameroon and the Congo increased to more than 50 percent.

“That was a little frustrating and disappointing,” Holman said. “I put a certain amount of stock in the idea of Nigerianness and even had conversations with friends of mine who are Nigerian. And I’d say, ‘Look at me, do I look more Igbo or more Yoruba?' And they would try make decisions about that. And we would share their Nigerian food. I didn’t tie a ton of my identity to that culture, but it was kind of a letdown.”

Looking Into The Past Means Confronting An Ugly Reality

Among some African Americans, there is a commonly held myth that their families have some Native American ancestry, said genealogist Kathleen Brandt. When she does genealogy presentations for an African American audience, about half of the attendees will claim having Native American roots.

"I was also told that we had Native American ancestry and we don't have a drop. I've got the records to prove that," she said. "If you can't follow a paper trail, you are not Native American."

African Americans will have a far greater percentage of European ancestry, Brandt said.

When Depradine also found that his grandmother has European ancestry, he probed government records to identify a few white men, some of whom were Quakers, who he is distantly related to. Given the brutal history of the slave trade, he wasn’t surprised to find those European roots.

“It’s part of us, whether we like or not,” Depradine said. “It’s painful; it sucks having to talk about how our grandmothers were treated long time ago. Unfortunately we can’t do anything about that in 2019 but just recognize that’s part of us and just don’t let those stories fade into oblivion.”

Crystal Williams of East St. Louis wants to take a month off of work to travel to the countries that her ancestors are likely from, according to the three DNA tests she had taken.

Crystal Williams, of East St. Louis, also was able to trace her ancestry to several European countries including Spain, England, France and Germany. She found it disconverting to confront the reality that her own ancestors were owned — an emotional cost that African Americans must bear when seeking information on their family history, Williams said.

“Your feelings are involved, and you have to set them aside,” she said. “I’m just looking for my people.”

Eric Depradine wants to share the ancestral stories he's learned through his research with his children.

Williams plans to take a month off of work soon to travel to some of the countries listed among the DNA tests she’s taken, including the European countries. Her results placed her ancestors all over Africa, but she’s not dissatisfied with having an incomplete answer about her ancestry.

“I think I can at least get back to maybe where the ship [carrying my relatives] docked, and that’s good enough for me,” she said.

Since his grandmother’s test, Depradine has collected many paper records about his relatives to see how far his family tree extends in the U.S. He’s motivated to use that research to share a rich family history with his children.

“I don’t want my descendants to think they don’t have any history here in the United States,” Depradine said. “We have a long history. We didn’t appear on this continent by accident. There were world events that shaped the reasons why our ancestors were brought here forcibly or voluntarily. I think it’s important my kids know they’re a part of that history.”
