Copernicus' father AND mother were of Polish Catholic origins. The mother may have had a German name but that was not uncommon at all throughout history. Especially when more Poles spoke German then Germans spoke Polish and there were/are more Germans then Poles.<quoted text>
She was from Warmia and didn't speak Polish. The royal families of Europe were ethnically mixed (and still are). His father was Polish by allegiance. But then there is no Polish ethnicity, only nationality.
Copernicus' mother's family were also related and connected closely to predominately Polish families not German families....so that says something right there.
Also both Copernicus' father's family and mother's family were STAUNCH Catholics. Its unheard of for a German to be Catholic in that part of North East Germany/North Western Poland where the German population was virtually ALL Protestant. There were Germans who were Catholics but they were on the other side of Germany in South/West Germany.
