I'm 4th Generation Italian on my Mothers side (Tuscany), Shes 100%. My Fathers side of the family have been here much longer, I'm not sure when they came over, but they lived in the south for a long time before my Grandama came to California. My Dad is 50/50 Dutch-Irish. So that would make me a 50% Italian and 25% Dutch and Irish.
Trace my family roots, and both my families are really, REALLY fuckin' old noble families that go back to around the time that the Canmores were murdering rival claimants and Scotland wasn't even a real concept; they were just the nobles that lived up north and had a royal family.
My ancestry, that I am certain of, is French-Canadian, Irish, and Czech (As in Czechoslovakia - I don't know whether it's Czech or Slovak) on my mother's side, and descended from a Scottish yeoman (probably with a fair amount of mix-ins) on my father's. Explains why we can't find a coat of arms for my family, actually.
