A study of the genealogy of Yakwac cattle camp reveals the features we have already noted as being significant in the genealogy of Nyueny. It is a lineage structure—the lineage being a branch of the dominant clan in the tribal area and that branch which is dominant in the district in which the camp was formed—to which are attached other lines through females, thus giving the genealogy a cognatic form, and affines. In order to graft themselves on to the tree of this dominant clan the linked families trace their descent through females at the points of graft lakwac Cattle

I would also draw attention to the different tribal origins of those Nuer in the genealogy who are not members of the dominant lineage, because they illustrate the movement of individuals and families which is so characteristic a feature of Nuer society: Y it was a Bui tribesman, he and Pinien being children of sisters or, as the Nuer say, a man and h isgatmanlende, his mother’s sister’s son; Carau and Wan-Wang were Jikany tribesmen, Carau being an aristocrat of the Lony section of the Jikany, though begotten by an Anuak; Nhial-Deng is of Thiang tribal origin; Kurcam was a man of the Jimem clan, a clan which is found throughout Nuerland and without a tribal territory of its own; and so forth. Indeed, it is necessary to point out that not all these outsiders attached to the lineage core remain attached to it. Nuer move about their country freely, and reside for some years with one lot of kin and then for some years with another.
