Well, I'm just American. I certainly don't give percentages, and instead of people giving percentages (which sounds ridiculous most of the time) why not just say, if someone asks you, "I have a Native American and Irish ancestral background" and leave it at that? I mean, if people ask me about my background, I just say that I'm a mutt, but from what I understand, I had quite a few Dutch ancestors. I think it's great if you can say you are an Italian-American, as you aren't Italian, per se, because maybe you have never even been to Italy, but you were raised in an Italian descended family and community in America, so you are an Italian-American. It's an American subculture. That's fine. But when you are just ordinary folk like me, whose family has been in America for who knows how long, then why bother claiming any sort of extra background? What's the point? My ancestors may have come from Holland, but that doesn't mean I know anything at all about Holland, have ever been there, or have had any Dutch traditions passed down to me. My maiden name was English, but that doesn't mean I knew anything about England before I got here or staked any claims on being English!
