Dude it's not as far fetched as it might seem. I remember something like one of the early Presidents has a grandchild still alive.
This is just one story from the first page of a google search. You can be sure there are more.

It is amazing to hear so many responses. Now I can say I am not the only
one. My Grandfather was born in 1860 on Colonel Haywood Hall's
plantation in Martin County, TN, and my grandmother was born in 1860 on
a plantation near Bowling Green, KY and was sold to a plantation in
Missouri. My grandparents met in Omaha where their families had fled
Klan violence and my father was their youngest, was born in 1898. He
lied about his age, saying he was one year older, to fight in World War
One and came back from the Western Front and the subsequent Red Summer
very radicalized. He joined th Communist Party and was an organizer in
the south. My mother was his 3rd wife, 33 years younger than he, and
they married in the 1950s then fled the country to Mexico because of the
McCarthy Era. I was their youngest, born in Mexico City on 1963. My
father died on my 21st birthday, when he was 87, in 1985.
Ironically, although I research slavery and the slave trade, I have
never done any of my own genealogical research. What I know of my
grandparents is from my father's stories to me, and he also published an
autobiography before he died.
Thank you, moderator, for allowing this personal thread, and thanks to
