A woman was left mortified to find out that her husband - and father of the baby she was pregnant with at the time - was actually related to her.
Marcella Hill, 41, shared her story on TikTok, revealing how she and her husband Tage found out that they were actually third cousins.
She admitted she'd "never publicly told anyone" that she and her husband are cousins, but decided to share the news to her almost 300,000 followers in one go - and the video has now racked up almost a million views.
Marcella began: "So I've never publicly told anyone but I accidentally married my cousin..."
Explaining how the shocking revelation came to light, Marcella continued: "I was sitting on the couch looking for names for the baby that we were about to have and I was on [genealogy site] FamilySearch."
She looked at names going back generations in her family, as her husband did the same for his own, hoping to find inspiration for a moniker for their impending baby.
"Husband's next to me on his own FamilySearch and he's like, 'Oh that's funny, we have the same grandma and grandpa's names.'
"I look at this line and it's all the same as mine. So I think, 'Oh no, no, you're still logged into my account.'"
It was then that Marcella came to the realization that no parents-to-be want to have... the reason she and Tage had the same names on their family tree was because they were actually relatives.
She continued: "Then we start looking at it and we realize my grandpa is his grandma's first cousin. So he calls his grandma and I call my grandpa and we asked them if they know each other.
"Sure enough, sure do. They lived together when they were growing up as children. We are third cousins."
Marcella also revealed that she and Tage had even won a prize for "being the closest related in a neighborhood activity" and the benefit of being third cousins is that they get to go to the same family reunions together.
Some viewers had questions about how the couple didn't realize they were related sooner - such as at their wedding.
They commented: "how didn't y'all realize this at the wedding?", and: "Did your grandparents not come to your wedding or any other family events before you were married?"
Marcella responded to the questions in a follow-up video, clarifying: "We got married at a courthouse after work on a Wednesday.
"Let's say we had the wedding, and my grandpa and his grandma were there, and we found out that we were third cousins at the wedding, what were supposed to do?"
Other followers were less worried about the pair sharing a gene pool, adding: "3rd cousins not a huge deal, you’re good, hilarious though."
Another wrote: "Hilarious!!! Why are some of you trying to shame her? 3rd cousins isn’t Flowers in the Attic."
One user also joked: "so in a way your baby is it’s own 4th cousin."
