I'm Armenian, Irish, French, German, Native American, and Indian. Mostly the first three.
Don't have any idea about my ancestors, like where they came from, what they did, or why they came to America and when. It was never something that I thought about looking up. The only thing I really know about any possible relatives are that there are a lot of Armenian people with the same last name as me living out there in America.
The only culture that I really know anything about and celebrate is my Irish side, since it's a big deal to my mother. Other than that, I just call myself a white American with an unpronounceable last name.
