Imelda: Because of the disruptions of what you might call normal tribal patterns, indians from many tribes moved into areas not usually associated with them. A person of indian descent in Santa Cruz county might be from Pima, Papago, Yaqui, Opata, Apache, or any number of other tribal groups. He might have ancestry from more than one tribe. I would think that you would have a better chance searching by name than by tribal group. Raclare
