Kin Groups and Descent. The present small size of the population and the limited information available on the Northern and Middle Andamans makes it difficult to create a comprehensive picture of Andamanese kinship. Earlier Ethnographic accounts present the basic tribal division as the "sept," but Radcliffe-Brown's observations lead us to believe that groups came together to ensure friendly relations. On the basis of Ongee ethnographic material and early descriptions of the Andamanese, it is beyond a doubt that the Andamanese have bilateral descent groups.
Kinship Terminology. The kinship system is cognatic and terminology, on the whole, specifies classificatory relations. Prefixes are affixed to classificatory terms of reference that also emphasize senior and junior age differentials.
