My last name is actually from Northern Ireland (the Protestant way of spelling it they say) although somewhere along the line they converted to Catholicism. Me, my dad, my grandfather, & my great grandfather for example were Catholics (that’s as far as I know for sure). Although me & my dad are lapsed agnostic Catholics.
I’m essentially a mutt of Western European ethnicities. Irish (the most), Italian, German, British, & some type of Scandinavian (although that’s just purely from a DNA ancestry test that I can’t really trace from people in my family).
