[Opinions] Re: Is it wrong to give your baby a tribal name if you're not from that tribe?
Wait.... Your husband is J.... And J is also married to this K woman? Or is K's husband a different person? I'm confused about this.
If J is of Aztec descent, and he's the father of K's baby, the baby will be of Aztec descent, even if it's half Caucasian. So it's fine for K to use the name on a cultural basis.
