Yes, quite a bit, but I don't particularly ~identify~ with that side of my family.
No. I have Catholic ancestry though.
All white people do, since before the 16th century everyone in Europe was Catholic.
I have 20th century Catholic ancestry. About a quarter.
Also that statement is not correct. The Sami tribes in northern Scandinavia were not Christianized until the 18th century and were converted to Lutheranism. And much of Russia wasn't Christianized until after the Schism.
Not to mention people from Jewish backgrounds (if you consider European Jews white, which not everybody does). Even plenty of Gentile families today are descended primarily from Jews who converted to Russian Orthodoxy or the Church of England or something a couple of centuries back.
