Kin Groups and Descent. The Xoraxané Romá recognize a bilateral kindred ( familja ) which, in theory, includes third cousins. In practice there is no rigid dividing line, and the composition will often depend on genealogical memory. This memory certainly reaches as far back as the third ascending generation, but for the most part only as far as the lineals are concerned; the collaterals are more easily forgotten. Within the kindred great stress is placed on the patriline, though this in no way constitutes a formalized corporate group. Eponymous ancestors do not exist. The patrilineal ideology, symbolized in the transmission of blood, is in evidence above all where blood feuds are concerned. The maternal uncle has a rather peculiar position: if his sister's son is killed, he can seek revenge (within certain time limits); sexual intercourse between himself and the wife of his sister's son is considered incestuous (whereas it is not considered so between a paternal uncle and his nephew's wife).
Kinship Terminology. The terminology makes a clear distinction between consanguineal and affinal terms. The consanguine terminology is of the Sudanese type with elements of the Eskimo type, while the affinal terminology is of a type that can be defined as "Greek," The terminological system is not, however, uniform throughout all Xoraxané groups.
