What about French-Canadians, or an Anglo-Canadian with mixed Native American ancestry? What about an Anglo-American with a Polish surname, or an Aussie with partial Greek ancestry, or aboriginal ancestry? I'm trying to get a read on just how similar a person needs to be, culturally or ancestrally, to be considered an offshore British person, by a "real" Brit.

There isn't a fixed line where you are or aren't British (or any other ethnicity).
Is an Englishman with a Polish name or partial Greek Ancestry British?
