Kin Groups and Descent. The system of descent is patrilineal, tracing back to a mythical ancestor who is believed to be a creator of the lineage. Until the nineteenth century the kuga kinship and naming system existed: each lineage, or kuga, had its own name, which was given to its male children shortly after birth. Members of each group had a particular loyalty to one another and sided with one another during arguments.
Kinship Terminology. Traditional kin terms follow the Omaha system insofar as a man will call his mother's brother's daughter "mother," and she will call him "son."
