Nothing quite as awkward as explaining to someone their grandparents were first cousins. Well, parents would be more awkward. #genealogy
@WaevetSmaevets Wow! Way before anything was really known about genetics, if people thought their own family had great qualities they'd keep marrying in the family to keep out the riffraff. That's why royalty have so many genetic conditions. Not saying that's what's going on with your ancestor.
