Liane and Marc met on holiday in the Bahamas when they were in their twenties. During their flight home to JFK, Liane had the sudden realization that Marc was The One.
After four decades and two children, the couple learned that theywere closerthan they thought.
“I got an email from the personalized genomics company 23AndMe with the subject line, ‘You have new DNA relatives.’ Which is how I discovered that my husband Marc and I are related through more than mere marriage,” Lianewrote.
“We’re third cousins.”
Third cousins mean the couple shares at least one great-great-grandparent. The situation doesn’t pose health risks, according to theGenetic Literacy Project.
But the same can’t be said of incestuous relationships between more closely related people.
Babies born of incest are at increased risk of suffering congenital disabilities, developmental delays, andgeneticdisorders, such as blindness, hearing loss, neonatal diabetes, and limb malformations.
In a separate case, a 30-year-old woman discovered that she and her long-term partnerwere actually biological siblingsthrough an ancestry test.

“I just found out that I’ve been dating my biological brother for 6 years,” the woman wrote on Reddit.
“Now I know that the comfort and familiarity is because he’s my brother. Not my half-brother. He is my full brother.”
“I discovered it when we did the DNA test thing to see our ancestry and what exactly we are. I ordered two for us; we spit in the tube and sent it out.”
“I’m just glad we both agreed early on that we don’t want to have kids. I don’t want to deal with the health risks and have to raise a child and [have] them know that their parents are siblings.”

Meanwhile, Virginia native Steve Edsel found out via AncestryDNA that his parents were first-degree relatives, either siblings or father and daughter, theDailyMailreported.
“That’s way, way more than I think many people would ever imagine,” Geneticist Jim Wilson said.
The study of incestuous relationships derives from the analysis of “runs of homozygosity,” or ROH: long stretches where theDNAinherited from one’s mother and father are identical.

Many people use ancestry tests to learn more about their family tree and find living relatives across the globe. This is what Kelli Rowletteintended to dowhen she sent her saliva kit to Ancestry.com.
Little did she know that the result would indicate that her father was not the man she’d grown up with but Gerald Mortimer, who she later found out had been her parents’ fertility doctor.
The doctor suggested inseminating Rowlette’s mother with a sperm cocktail containing 85 percent of Fowler’s “genetic material” and sourcing the rest from a donor.
But these quick DNA-testing methods–which cost approximately $130—have also brought positive news.
Last year, adopted siblings Frank and Victoria discovered that they were biologically related.
When their adoptive mother told them the truth about their family origins, Frank and Victoria decided to investigate their history throughDNAtesting from Ancestry.com.
“I got the match that my brother had popped up as my full sibling, my biological brother,” Vicky toldCBS News.
“We were both found a year and a half apart and wound up in the same family,” Frank revealed. “The odds are insane.”
“I suspect this happens more than we think,” someone wrote
