Real Life Siblings From Netflix's 'Our Father' Doctor Says They're Worried About Dating Siblings

Real life siblings from Netflix's Our Father documentary have revealed their fear about themselves and their children unknowingly dating a potential family member.

True crime doc Our Father focuses on the twisted crimes of Donald Cline, a former fertility doctor who fathered dozens of children by artificially inseminating his own sperm into women without their knowledge or consent in the 1970s and 80s.

At the time the Netflix feature was released, there were 94 children who had been fathered by Cline.

In light of the film landing on the streaming service, two of the infamous fertility doctor’s children, Jason Hyatt and Jacoba Ballard, appeared on This Morning on Wednesday, May 18, to discuss the jaw-dropping tale.

Hosts Holly Willoughby and Phillip Schofield interviewed the siblings remotely in the US and asked how the bombshell news has affected themselves and their families.

Holly, 41, began: “There’s so much going on for you. But I guess there’s other things to consider here as well.

“Once you realise there’s lots and lots of siblings all in a 25-mile radius, then I guess there’s the risk as well of inadvertently meeting a sibling, having a relationship with a sibling.

“Even now, 94 and counting, that list isn’t over. This still could possibly happen. Is that a very real thought?”

Responding to Holly’s question, Jacoba admitted: “Not for siblings only, but for kids. Kids that are older that meet an aunt or an uncle, not just a cousin.

“We’ve never been told when he started or when he stopped. We know he retired in 2009, so we could have siblings as young as 2009, 2010.”

ITV viewers were horrified by Cline’s scheme, which wasn't illegal at the time in Indiana but, as a result of Jacoba and her sibling’s campaign is now illegal in the state, and took to Twitter in their droves to share their disgust.

One penned: “I watched the documentary the other day and it's appalling, disgusting and unbelievable.

"The abuse of his profession and the fact the judge pathetically let him off is an insult to all these people."

"This is horrific,” another wrote. "I watched the documentary last night. How there has actually been no felony is absolutely beyond me. These poor families have been torn apart by this sicko."

A third commented: "This is totally bizarre and just sick."

Echoing many previous comments, a fourth shared: "This is just terrible! These poor people!"

Our Father is available to stream on Netflix now.
