What is the most amount of children you know someone to have had?

I mean personally know them, not that you saw some article online of a guy with 50 wives lol

For me it's a guy with 7 kids, only one of which is male. Seems his genes heavily favour the x chromosome.

How about you? Who do you know with the most children?
