and the mother's sister by the same term as the mother. The mother's 

 sister's husband is called by the same term as the father, and the 

 father's brother's wife by the same term as the mother, as in Chicka- 

 saw, for instance. There is a distinct term for mother's brother as in 

 all the systems we have been discussing]:, and a distinct term for father's 

 sister as in Cherokee and northern Choctaw. The mother's brother's 

 wife, however, is called by the same term as the father's sister, and 

 the father's sister's husband by the same term as uncle. The father's 

 sister's sons and daughters are classed with the sister's sons and 

 daughters because, descent being male, their mothers belong to the same 

 clan. In both cases those in the next generation are grandchildren. 

 Conversely to the case in the Crow system, the male descendants of 

 mother's brothers are all called mother's brothers. The daughters 

 are classed with the mother, their children with sons and daughters, 

 the children of these with uncles and nieces depending on the sex, 

 and the children of all with uncles and grandchildren. This appears 

 somewhat confusing, and it is to be suspected that descendants of 

 uncles falling outside of the clan were reckoned in the categories. 

 There are distinct terms for father-in-law and mother-in-law, and as 

 in most of the systems already considered except Creek, son-in-law 

 and daughter-in-law relations are covered by a single male and a 

 single female term. A man employs one term for his sister's husband 

 and his wife's brother, and a woman uses the same for her brother's 

 wife. The man has another for his brother's wife and his wife's 

 sister, and the woman uses the same for her husband's brother and 

 her sister's husband. 



Of all the Southeastern systems of which we have information 

 in any way satisfactory, Caddo is the most divergent. Like those we 

 have been considering, it has one term for grandfather, one for 

 grandmother, and one for grandchild, except that each sex uses a 

 different expression for the last-mentioned relation. The father's 

 brothers and the mother's sisters are also classed with the father and 

 mother respectively though older and younger individuals of these 

 groups are discriminated. As in the systems considered, there is 

 also one term each for the son-in-law and daughter-in-law. Differ- 

 ences appear, however, in the fact that a reciprocal term is employed 

 between father-in-law and son-in-law, and that the same term is used 

 for mother's brother's wife as for son's wife. The most striking 

 difference is in the extension of the terms for elder brother, younger 

 brother, and sister over the children of both the father's brothers and 

 sisters and the mother's brothers and sisters (S wanton, 1942, pp. 

 166-170).
