With the explosion in genealogy testing, Americans are unearthing shocking family secrets hidden in their DNA
When Linda Ketchum of Glendale, California asked her husband for an AncestryDNA kit for Christmas, it was just a lark. She had no family secrets she was trying to uncover, no genealogy mysteries that needed answers. She was just curious.
“My dad was German and my mother was Scottish English,” she says. “I thought it’d be fun to learn a little about my genetic ethnicity, to trace how all the pieces came together.” But she ended up getting far more than she bargained for.
When she went on the AncestryDNA site to view her DNA matches, there were no connections between her and her father. Even more unsettling, at least two-thirds of Ketchum’s matches had Hispanic surnames. “At first I didn’t believe it,” she says. “But then I kept re-checking it, and I realized, oh my God, does this mean I’m… I’m Hispanic! All these years I thought I was German on my dad’s side, but all of a sudden it was dawning on me that my dad wasn’t my real dad and I had an entirely different ethnicity.”
At 51, half a century into her life, Ketchum’s familial and cultural identity had changed in an instant. “I looked in the mirror and I didn’t know who I was anymore,” she says. “Every Hispanic person I saw on the street, I thought, ‘Are you my cousin?’”
As an only child whose parents were both deceased, she had nobody to turn to for answers. So she kept searching on AncestryDNA. She finally discovered the identity of her biological father, Bill Chavez of New Mexico, who had died when Ketchum was just seventeen.
“It kind of consumed me,” says the mother of eight. “I still wonder sometimes, would my life have been different if I’d known this earlier? My real father, my actual grandparents, they all spoke fluent Spanish. I can’t even speak a word of it!”
She joined a secret Facebook community called DNA NPE Friends—NPE is short for “Not Parent Expected”— and found not just the support she needed, but a reminder that she’s far from alone.
“I never realized that there are so many others,” Ketchum says. “All over the country, DNA is blowing up family secrets.”
Business has never been better for what’s often called “recreational genetics.” The number of people who’ve had their DNA analyzed — which involves mailing your saliva or cheek swab to a genetic testing company like 23andMe, AncestryDNA, Family Tree DNA, or My Heritage — doubled in 2017, with more than 12 million customers, or roughly 1 in 25 American adults paying to have their genes decoded.
What these companies are offering can sound tantalizing to anybody with even the mildest interest in genealogy. For just $100 — the average cost of a direct-to-consumer genetic genealogy test — you can “Learn a more complete story of you,” as AncestryDNA’s website declares, or “Find new relatives you never knew existed,” promises 23andMe.
It’s only when you get to the fine print that the possibility of a genetic bombshell becomes more apparent: “You may discover things about yourself that trouble you and that you may not have the ability to control or change,” warns 23andMe’s Terms of Service statement.
This burgeoning genealogy-on-demand marketplace — which some projections claim could be worth an estimated $60 billion in sales by 2020 — has spawned its own unique syndrome. Call it PTDD: Post Traumatic DNA-Test-Results Disorder.
The NPE Facebook community, launched by Catherine St Clair last summer, is already up to 2,364 members (at press time) despite a rigorous screening process. (You can’t join the group unless you’ve actually gotten the DNA rug pulled out from under you. Lurkers need not apply.)
“People don’t get that it really is a significant trauma,” says St Clair, a 56-year-old Texan who discovered through Ancestry.com that her biological father wasn’t the same person who raised her. “You feel completely alone and isolated. It’s like having an infection that’s deep under your skin that keeps festering and it’s painful and it’s getting worse and worse. Only after it’s exposed to air can it start to heal.”
Because the home genetics industry is still relatively new — the first tests didn’t become commercially available until 2007 — there isn’t research on the long-term psychological effects of getting bad DNA news, says science writer Carl Zimmer, author of the newly-released book “She Has Her Mother’s Laugh: The Powers, Perversions, and Potential of Heredity.” But, he adds, “there’s evidence that some people may end up grappling with test results for a long time, especially if they didn’t prepare themselves for the possibility of a surprise.”
The fallout from discovering that your genetic identity isn’t what you expected isn’t just an internal struggle. Friends and family can be less than supportive. Cleon Brown, a police sergeant in Hastings, Michigan, filed a legal complaint against his department last year, claiming that after learning of his African heritage on Ancestry.com, his colleagues targeted him with racial harassment. (Just last month he won $65,000 in damages.)
Most revelations don’t result in lawsuits, but not every family is delighted to find out they have a new relative. “More than half of NPE members have had the door slammed in their face,” says St Clair. “People want them to go away and they say things like, ‘Why are you doing this? Why are you airing dirty laundry? This is a secret you shouldn’t be sharing!’ It hurts because nobody wants to feel like a dirty secret. We’re not trying to stir up trouble. We’re not trying to wreck a family, we just want to know who we are.”
Natalie Frobel, 32, from Las Vegas, NV, had an uphill battle after getting her DNA test results. “I found out I was conceived using an anonymous sperm donor,” she says. When she shared the discovery with her parents, they were initially argumentative and dismissive but eventually admitted the truth. “I don’t remember which parent said what, but one of them said to the other ‘We should just finally tell her,’” Frobel says.
Things became tenser when Frobel announced that she wanted to track down the donor who helped conceive her because she’s been diagnosed with the autoimmune disease Lupus and wanted more information on her biological father’s family medical history. During one especially heated discussion, her mother “tried to argue that it was nothing like adoption and the stranger’s DNA didn’t matter,” Frobel says. “I argued back that it very much did matter, and at some point in the conversation she yelled out, ‘I almost wish I didn’t have another man’s sperm in my vagina to conceive you!’
“I haven’t seen my family since,” Frobel says.
Sometimes DNA results don’t just reveal unexpected dads, but new siblings. Roberta Estes, a genetic genealogist who helps people translate their DNA results, says she’s consulted dozens of people who’ve discovered so-called “secret siblings”, proof of their father’s (and sometimes mother’s) infidelities. The choice of whether or not to reach out to these half-brothers and sisters is always a difficult one, she says, as the reactions are never predictable. “Some people are accepting,” Estes says. “Some people are disbelieving, some people are angry, some people grieve the person they thought they knew and didn’t. Some people are incredibly grateful to find a sibling.”
When St Clair learned that she was conceived during an affair and had two half-sisters she’d never met, she reached out to them and “neither ever made me feel bad about the infidelity of their father,” she says. “They’ve been totally non-judgmental and supportive.”
To further complicate matters for those grappling with unsettling DNA news, there’s also the question of accuracy. DNA testing is far from a perfect science, says Sheldon Krimsky, a professor at Tufts University who studies the bioethics of genetic engineering. “There’s really no oversight for ancestry testing,” he says. “There’s no independent testing that validates any of it with scientific certainty.”
When these DNA-testing companies have been tested, they haven’t exactly passed with flying colors. In a study published last March by researchers at Ambry Genetics, a medical laboratory in California, they analyzed the results of commercial DNA tests (without naming specific companies) and found that only 60 percent of the findings could be confirmed.
The technology is a far cry from what we see on forensic crime shows on TV, “where they find the DNA and instantly identify the perpetrator,” says Robert Green, a medical geneticist at Harvard. “Most of genetics is about probability. If you look at it through that lens, you see why it’s both valid but also kind of disappointing. On average, DNA testing companies are telling you the truth. They’re telling you that they’ve identified markers that indicate a high probability that you come from X region. But that’s still just a probability and it’s far from a certain.”
Robin Smith, who heads 23andMe’s ancestry program, doesn’t agree that their service is mostly about probabilities. “We see your results as being a living analysis,” he says. “Here’s the best we can give you right now based on the algorithms and reference data sets that we have available. But it is something that’s continuing to improve.”
Whether entirely accurate or not, modern DNA tests are changing lives. But is it for the better?
AJ Jacobs, author of “It’s All Relative: Adventures Up and Down the World’s Family Tree” — in which he attempted to make contact with the 80,000 (alleged) distant relatives he only learned about because of DNA databases — believes genetic sleuthing can bring us closer together. “The hope is that it’ll show us that we’re all a mix,” he says. “We’re all mutts. There’s no such thing as ‘racial purity’. I’ve seen many instances of it increasing tolerance. There was the Texas meteorologist who found his biological mother through DNA testing. He’s gay and she’s evangelical Christian. It could have gone terribly. But his mom overcame her bias and fully accepts him and his husband.”
Deborah A. Bolnick, a geneticist at the University of Texas at Austin, isn’t surprised with the rising popularity of DNA testing. “So many people in this country are immigrants,” she says. “We’ve always been interested in where our ancestors came from.”
But there is a limit to what this information can tell us about ourselves. “We put too much cultural stock in DNA,” Bolnick says. “Our identities are shaped by a lot more than just what we inherit from our parents or grandparents.”
Even Smith, a 23andMe employee, agrees. “We’re telling you about your DNA,” he says. “We’re not telling you about your identity or how you should behave or how you should think about yourself. DNA is just one piece of the overall puzzle. If DNA provides a useful lens for thinking about yourself, I think that’s great. But it definitely isn’t the end of the story.”
Linda Ketchum is proof of that. Since learning about her real father and ethnicity, she hasn’t changed much about the way she interacts with the world. If she’s changed at all, it’s in small ways.
“I see my dad in every reflection,” she says. “The things I used to explain away, like that I was the only one in my family with black curly hair, make more sense. My grown-up sons, they’re the spitting in image of their grandfather.”
Although there are no survivors of what she assumes was an affair between her mother and Bill Chavez, she claims she’s had “flashbacks” since learning about her real dad. “I remember my mom bringing me to Bill’s house when I was really young,” she says. “I can so clearly see myself in that kitchen, Bill is sitting at the table, and there’s another woman there in a pink housecoat. She’s friendly but not warm. I remember his wife’s name was Rose. I don’t know if the woman I met was his wife.”
She’s also gone from having one first cousin to thirteen new cousins. When she initially reached out to them, “they weren’t welcoming,” says Ketchum. “One of them was very suspect of me, a woman who lives about ten miles from me. But once I told her I’d taken the Ancestry DNA test, she was like, ‘Oh, I’ve always wanted to do that.'” When the cousin took a test herself and learned they were actually related, the two women have become, well… like family.
Because of her experience, Ketchum says she’s started to look at her personal identity as a brick wall. “When we learn something that’s devastating or life-changing, it knocks some bricks out of the wall,” she says. “The wall weakens but it doesn’t tumble completely. You’ve just lost a few bricks, but the foundation is still there. And you find some new bricks to replace the old ones.”
She laughs at her own explanation. “It’s a silly metaphor, but it makes sense to me,” she says. “I’m still figuring out how to wedge those new bricks in there. But my wall isn’t collapsing anytime soon.”
