I've heard a lot of native people won't donate for those DNA tests, so there isn't many to compare against. Doesn't mean his family is lying.

My mother is half Chiricahua and also had a DNA test and it shows no native DNA but my grandmother is registered, as far as I know. I think my grandmother's brothers do (or did, not sure if still alive) live on a reservation.

Also, DNA passing isn't always a perfect mix. Maybe you get a little more of A, a little of B, none of C but your relative does get some C.
