Kin Groups and Descent. Beyond the family, the most important kinship groupings were patrilineal exogamous totemic lineages, each of which was connected to one of two patrilineal moieties; only among some of the Foothills Yokuts subtribes was the moiety organization absent. Subtribal offices and responsibility for certain ceremonial functions passed within lineages. Moiety members had reciprocal ceremonial obligations and formed groups for opposing teams in games such as gambling, races, and hoop and pole contests. Patrilineal descent was the norm.
Kinship Terminology. Valley Yokuts group kin terms followed the Omaha pattern; Foothills Yokuts terms followed the Hawaiian pattern.
