One notable Idoma scholar E.O. Erim cites genealogical data, collected from most modern groups in Idoma suggesting that they derive from several ethnic groups, each with different historical origin. Furthermore, the available genealogies indicate the existence of diverse ethnic groups who descended from ancestors other than Idu. In several of these cases, the claim of common descent is backed by both extensive genealogical connections and possession of common kinship totems. Erim contends that while Idu was certainly a migration leader—he was not the “father” of the Idoma in the sense implied in the above traditions. These two considerations make it difficult to simply accept the view that every group in Idomaland is descended from Idu.
