Forum:Pier Gerlofs Donia descendants and ancestors?

Who are the ancestors of the legendary Frisian warrior, warlord, freedom fighter and folk hero Pier Gerlofs Donia (1480-1520)? Where do they live nowadays? I heard some live in the Netherlands, others live in the US. I know he had a daughter and a son, both of whom reached adulthood and where raised by either his sister or his mother. What happened to them, who where there decendents and were do these decendents live?
