Re: Two things
"Still, I'm not one of the indigenous people myself so I'll let them choose their own name. "
You'll probably find they already have. Each grouping in it's own language. You'll often find that a native peoples name for itself translates in English to "the people" or similar and the name for other peoples not of their group often translate to "others", "outsiders", "strangers" or similar, sometimes with overtones of inferiority since they are not "The People".
