In a twist of fate, two sets of twins ended up marrying and now their children are genetically siblings

Venessa and Kerissa Sealby never thought that they were would end up marrying another set of identical twins.

Not even just that, but the pair thought that the prospect of it made them feel ‘creeped out’.

But it turned out that in the end, this is exactly what would end up happening after the pair met identical twin brothers Lucas and Jacob Sealby.

Venessa, 28, told “We didn’t have any interest in dating twins. The idea kind of creeped us out, like no, that’s weird. And physically we had completely different types.”

Venessa had been working as a personal trainer in June 2020, and a client told her about the brothers.

“She was like, ‘You and Kerissa ran track at University of Oregon, they ran track at Washington State, and I think you’d be a perfect match’,” said Venessa.

The two sisters married a pair of identical brothers.

“I told her, ‘You can give him my number, but I’m not going to reach out to him.’ And so that’s what she did.”

Venessa found that she had gravitated more towards Lucas, while her sister Kerissa felt a spark with Jacob.

Venessa said: “We’re both the outgoing twin. In high school, I spoke for Kerissa and he spoke for Jacob.”

She added: “As soon as we got in the car, I looked at Kerissa and said, ‘I’m calling mom, because I’m marrying that man,’”

Kerissa and Jacob began dating, with Kerissa saying: “Jacob and I had a one-on-one date and I was like, ‘OK. This is actually happening’. The whole thing seemed so crazy.”

The two couples also live very close to each other and see each other nearly every day.

The babies are technically siblings.

Kerissa said: “We live two steps away from each other. We’re constantly running back and forth to each others houses.”

She added: “I’m at Venessa’s probably 10 times a day.”

And things have only gotten bigger since both couples had children together.

In an unusual set of circumstances, that means that their children are both cousins and genetically, also siblings.

That’s because if your parents are genetically the same, as would be the case in two sets of identical twins, then you are technically a sibling.

Medical geneticist Dr Robert Green works at Brigham and Women’s Hospital in Boston, and said: “Even though they have different parents, they’re genetically full siblings.”
