What's your Ethnic, Racial, National background?

I'm White American and I am of mixed heritage. Italian, Irish, German.

I'm Canadian and Irish from my mother's side (most of whom fit the Irish stereotype too well). I'm not sure of the specifics on my father's side. He's white (same as my mother), but he was adopted. He was born in Quebec, his father was British and I'm not sure about his mom (I'm referring to his non-biological parents). I just like to assume I'm a mix of all breeds; that way I can make terrible racial remarks without feeling bad about myself.

Canadian, pretty much 50/50 mix.  My dad's side of the family is entirely Ukrainian, my mom's side is German (via Russia and Czechoslovakia, they've been migrating eastwards slowly since the 1500s).  There could be some Metis blood in my mother's side, but if so it's no more than 1/32.  Enough detail for you?

I'm a white ass Australian with mixes of French, Dutch, South American, and English. I'm the second generation of my family born in Australia.
 
Waay back in Assassin's Creed Time (or so it seems), one of my great-great-great-great et et et etc grandmothers was a whore that was having an affair with the greatest and most famous Naval officer and land discoverer of his time. I couldn't be bothered finding out the guy's name. My family has had other achievements since, more than being sluts, but I just wanted to share something unexpected.
