Decades after a fertility doctor used his own sperm to secretly populate parts of Connecticut, a woman took a DNA test and uncovered a horrifying truth about her high school sweetheart – he was her brother.
As at-home DNA kits continue to help people trace their biological roots, Victoria Hill decided to explore her own origins out of curiosity.
The search quickly uncovered far more than the Connecticut woman expected, revealing dozens of previously unknown siblings beyond the brother she grew up with, a number that has continued to rise as more people come forward.
Some reached out with “horrifying” information, like the message from her former boyfriend Ethan: “You are my sister,” he wrote, according to her story published by the Daily Mail.
The message included a screenshot from a DNA testing website that confirmed the truth.
‘Utterly devastated’
Hill, now 41 and a licensed clinical social worker from suburban Connecticut, described her relationship with Ethan as a typical young romance, unaware of the biological link between them.
“I was utterly devastated. I couldn’t sleep for days. I kept having flashbacks to the special times we’d shared…it was all tainted. Of course, when we’d got together, we’d had absolutely no idea we were related – or that there was even the remotest possibility we could be,” she wrote, adding the two were “teenage sweethearts” and had a sexual relationship between the ages of 17 and 18.
Years later, fate placed them in the same room again. “When we bumped into each other at a friend’s wedding in our mid-20s, I was struck by a wave of emotion and wondered whether we should rekindle our relationship,” she continued.
That moment passed without anything happening, a detail Hill now sees as life-altering. “Thankfully nothing happened, and I met my husband Ben shortly after. But things could so easily have gone the other way.
“What if Ethan had become my husband and father of my children? It’s unthinkable. The idea that I’ve been intimate with my own half-brother is torturous enough.”
Fertility scandal
The explanation behind the shocking discovery traces back decades, to fertility treatments carried out in the 1970s and 1980s.
At the time, secrecy surrounded such procedures.
“That way, if they did get pregnant, they would never know for sure who the biological father was. They were advised never to tell their children, too,” said Hill, who explained her mother believed the clinic had used sperm donated by a Yale medical student. “DNA tests weren’t available then, so paternity could not be proven either way.”
But once technology made DNA testing available, Hill and Ethan learned their mothers had both been treated by the same doctor.
Doctor populated parts of Connecticut
The truth, however, proved far more disturbing. The Yale fertility doctor, identified as Dr. Burton Caldwell, died at 86 in February 2025 while facing a lawsuit accusing him of using his own sperm to inseminate patients over two decades. Hill and her mother were part of that lawsuit.
“I’d been intimate with my sibling. I’d unknowingly committed incest” Hill said about learning that her and Ethan shared a father.
“He had told both [women] they’d received sperm from an anonymous donor. But that donor had in fact been him,” the mother of two writes.
“It turned out he had been secretly donating his own sperm to his patients for 20 years. Not only is this morally reprehensible, flying in the face of any code of ethics, but there have been grave consequences for me, my family and his many other offspring.”
Web of unknown relatives
As DNA testing continues to connect people, Hill has uncovered the scale of the doctor’s actions. “At the last count, I had 25 half-siblings – 14 sisters and 11 brothers – and consequently there are more than 50 first cousins in our vicinity,” she shared in the April 2026 essay.
“But more are always coming forward. In fact, as well as Ethan, I’ve recently learned I had two other half-siblings at our school – one sister and another brother. This increased my chances of unwittingly having a relationship with a close relation.”
The realization didn’t just reshape her past – it left a lasting emotional impact that continues to follow her.
“I was traumatized by this,” Hill told CNN in a 2024 interview. “Now I’m looking at pictures of people thinking, well, if he could be my sibling, anybody could be my sibling.”
Historic case
According to CNN, Hill’s case highlights the severe consequences tied to fertility fraud, where doctors deceived patients by using their own sperm without consent.
Her experience underscores how loosely regulated practices in past decades created large, untraceable biological networks, increasing the risk of close relatives unknowingly forming relationships.
For those advocating stricter laws, her story has become a defining example of how serious the issue can become.
“This was the first time where we’ve had a confirmed case of someone actually dating, someone being intimate with someone who was their half-sibling,” Jody Madeira, a law professor at Indiana University and an expert on fertility fraud, told CNN.
Children face a ‘serious issue’
For Hill, the consequences do not end with her own experience. She now worries about the future her children will navigate.
“It’s a serious issue for my children,” she writes about her two kids, now 10 and 5. “Should they stay in the area, they will need to ask potential partners to have DNA tests to avoid unwitting incest with unknown cousins.”
