Kin Groups and Descent. Although descent is patrilineal, genealogies are not remembered after three or four generations. Patrilocality is very strong, however, and people are believed to have remained patrilineally grouped since the time of their arrival in the country. Thus, most villages consider themselves ultimately to be agnates and abide by the law of exogamy.
Kinship Terminology. The Rukuba use Hawaiian cousin terminology with bifurcate-merging terms for maternal uncles.
