lol, I'd say you are pretty much Irish, but he was born in Poland and emmigrated to America as a child with his parents who were born in Poland also, how does that make him American?
He has lived in America during his formative years, been educated in America, practises American customs, experienced American culture (probably has an America accent) and probably calls Florida home.
I don't see how he cannot be considered American.
I have Irish heritage but I consider myself English since the majority of my family are English and were born in England, had I been born in Ireland and moved to England as a child I would still consider myself Irish.
In that scenario, you would be Anglo-Irish.
I should have known you had Irish heritage, you're too logical to be anything else unlike the rest of these maniacs ;)
P.S. Do you remember what Wellington said? ;-)
