How far back should we go?
immediate few gens (up to 4) = American(by birth), Mexican.
next few gens (5 to x) = Native American, English, Spanish, Irish, French, German, maybe more?
even further back (x+1 to y) = Roman, Visigoths, Barbarians, Caucasian.
finally as far back as possible (y+1 to beginning of Species) = African.
