Genealogy / I'm polish and have a darker complexion - WHY? [78]

No, they don't. If I met a person looking like the one on the photo you provided I would assume that it's an immigrant. When I was still in school I used to be the only person with dark hair in class and people were always surprised when I told them that it's my natural hair colour. I think it all depends on which part of Poland someone comes from.
