Finding a common ancestor on both sides when doing ancestry

Hear me out Six degrees of separation exists for living people, I never once considered genetically.
My nanny asked that I spend a little time piecing together everyone's names and history. After going back a very long ways, I find a guy who appears on both sides of her mother's family tree.
So basically, her mother's grandmother's ---great great great great grandfather
...and her mother's father's --- great great great grandfather.
Were the same person.
I tell my wife, and her response is immediately "that's disgusting"
But after viewing the family tree blown up... I don't really see how they could have kept track of it. Separated by at least 120 miles and 5 generations, neither had a last name that had been linked again in 5 generations.
At this point, I bet my wife, who is from 2000 miles away, we have a common ancestor. Seven generations back, there it is. I pick a random dead celebrity at that point, eight generations back for me.
Kind of creepy to think about

My family came to this country along bayou LaFourche in 1782. Along with 6 other families.
We have to have some interbreeding for the first 50yrs. I rather not know.

It’s more of an emotional reaction. Genetically it’s not a big deal when it’s that far apart.

We all related if you go back far enough

It certainly explains a lot about how you are today

Second cousins only share 3% DNA. That’s not high at all.

My first wife and my second wife were somehow both born in the same town 2000 miles away. My wife doesn't know it, but I'm like 99% sure they went to k-3 together

Welcome to Kentucky, cousin fricker.

I mean if we started out with only two people then their offspring had to procreate with each other or the parents procreated with their own children.
For the Adam and Eve thing to work there had to be a lot of incest.

Your wife is mathematically challenged.

Reminds me of the ole Kentucky joke,
“Thank goodness my parents divorced so I could marry my wife. Can you imagine if my parents had remained married and I married my sister.”
Ok, I paraphrased the frick out of it, apologies

There are small towns in Louisiana, looking at you Jonesville, where everyone is related somehow.

when my wife and I were doing wedding invitations we found one name that both of us had from the list on both sides' parents' names and addresses. we grew up about 2 hours away from each other, but didn't have any common acquaintances outside of our college friends
we had a quick stare at each other
she asked her mom who it was and it was her mom's cousin.
my mom said that it was her next door neighbor growing up.
sigh of relief.

If you start doing the math on generations, it becomes quickly apparent that there HAS to be MANY shared ancestors across different branches. 30 generations is like a billion people.

I got a vacation for asking about breeding between people that don’t know who theirs fathers are so be careful

After 4 generations you’re good

Everyone has two parents, four grandparents, and 8 greats, etc., doubling each generation. In forty generations, back about 1200 years, your number of ancestors would total one trillion, far more than all the humans who have ever existed. The global population in 800 AD was no more than 200 to 300 million. Mathematicians have calculated that all with European ancestry have a common ancestor within that time frame, and more likely within the past 500 to 600 years.
