My mother was half Italian, Half Irish. No more no less. My grampa comes straight out of Sicily and my gramma, Ireland.
As for me even though I am 70% Irish, 20% Italian, 10% other ethnic backgrounds, I feel more Italian.
Btw, the reason my Irish outweighs everything else is because my father was many things (hence the 10%) AND Irish so the Italian is outweighed
For my grandpa on my dad's side, the family has been ethnically confused for generations. Many generations ago, a father changed our name from Rav________ to Rav___. He misplaced the document stating the change or something and in the sixties, my great uncle found it somewhere. My dad's side was under the impression they were Italian for generations. Turned out they weren't
EDIT-Apologizies if it went off track, Celeste. Typed in what I knew.
