Kin Groups and Descent. In A.D. 1769 an estimated fifty to seventy-five patrilineal sibs existed as named groups, each descended from a mythical ancestor. Each village, or band, had ten to fifteen sibs represented by a lineage within which descent was traced and kinship terms used. A sib managed Inheritance only if family or lineage lacked direct heirs. The sib system facilitated visiting and movement between bands and ecological areas.
Kinship Terminology. While data are unclear, a variant of the Omaha system seems to have existed.
