Found the bad link in someone's genealogical path to Charlemagne. Mother born in 1382. Son born in 1390. Not likely.
@poemblaze I came across a closed loop in my genealogy, back in the 1700s. It was a few generations wide, but it was a loop nonetheless.
@NoahPaulLeGies ala "I'm my own grandpa?"
@poemblaze As in, "Isaac and Mary had two boys, John and Robert. John had a son, Robert, who married Robert's daughter, Mary."
