Kin Groups and Descent. All members who are related to each other by birth or by marriage, even if they are not all living together at the same place, form the kin group. Descent is patrilineal, and the members of each kin group believe they have descended from a common ancestor. The clan or maximal descent group ( khilli ) is divided into lineages and sublineages.
Kinship Terminology. A classificatory system for addressing kin is used. Thus the same relationship term is used for addressing persons of the same generation and sex in many cases.
