[6] Russian mirs, South Slavonian "joint" families, Corsican clans with their vendettas, and tribes in the Caucasus still have the group interest strong, and the feuds of the mountaineers in some of the border states illustrate family solidarity. [7] "In all the tribes with whom we are acquainted all the terms coincide without any exception in the recognition of relationships, all of which are dependent on the existence of a classificatory system, the fundamental idea of which is that the women of certain groups marry the men of others. Each tribe has one term applied indiscriminately to the man or woman whom he actually marries and to all whom he might lawfully marry, that is, who belong to the right group: One term to his actual mother and to all the women whom his father might lawfully have married."--SPENCER and GILLEN, _Native Tribes of Central Australia_, p. 57.
