To my knowledge, I have no South Asian ancestry at all. My mother's side is French, my father's side is French-Danish, I was raised with Telegus for a short while and I work in a primarily Japanese art medium.
I taught French in college, in theory, but actually taught more students Spanish because they were the ones who kept coming in for help. And when you know one Romance language you pretty much know them all.
I get asked a lot if I'm Irish. To my knowledge, I have no Irish in me at all.
