It depends how you want to term it. My grandmother was born in Canada and grew up on a homestead in northern Alberta. Both her parents were from what is probably now Ukraine (one was in Austro-Hungarian territory, Galicia, for sure and which would now by in Ukraine, the other we don't really know; they were both Ukrainian-speakers, though). My dad's father died when he was five. He knows very little about his background short of names and my grandmother's word (which wasn't kind to them, there is some Romanian and possibly even Romani in there, but a lot of its speculation). His mother (my grandmother) was second generation (from my understanding of the word) and she raised him (she was fluent). First generation tends to mean someone born elsewhere who moved here from what I know (that's my understanding, maybe I'm wrong). That would make my dad third generation. That's my understanding of it, anyway.
