R. H. Mathews argued that the Tjial, together with two other tribes of the Victoria River Valley, namely the
Bilingara and
Kwarandji, shared an identical classificatory pattern for intermarriage. Mathews argued that the system, classifying women into two cycles, each having "perpetual succession within itself," was one characterized by
matrilineal descent. His schema, he claimed, was quickly adopted by
Francis Gillen and
Baldwin Spencer in their analysis of the class system of the
Bingongina, which however redeployed the pattern to argue that the latter had but two
moieties exhibiting
patrilineal descent. A controversy over the interpretation of these data sets arose, with
A. R. Radcliffe-Brown effectively winning the day by arguing that the quarrel over matrilineal/patrilineal descent was confused by a failure to appreciate that "descent" in the abstract is meaningless, unless one takes into account the intricacies of class, phratry and totem relations, and irregularities in the overall system. ==History of contact==
