Maternal law is likewise shown to have existed in the fourth book of Moses, 32, 41. There it is said that Jair had a father of the tribe of Juda, but his mother came from the tribe of Manasseh, and Jair is explicitly called the son of Manasseh and became heir to that tribe. In Nehemiah, 7, 63, we find still another example of maternal law among the ancient Jews. There the children of a priest who married one of the daughters of Barzillai, a Jewish clan, are called the children of Barzillai. They are, accordingly, not called by their father’s but by their mother’s name. In the Punaluan family, according to Morgan, one or more series of sisters of one family group married one or more series of brothers of another family group. A number of sisters or cousins of the first, second and more remote degrees were the common wives of their common husbands, who were not permitted to be their brothers. A number of brothers or cousins of various degrees were the common husbands of their common wives, who were not permitted to be their sisters. As inbreeding was thereby prohibited, this new form of marriage was favorable to higher and more rapid development, and gave those tribes that had adopted this family form an advantage over those who maintained the old form of sex relations. The following system of kinship resulted from the Punaluan family: The children of my mother’s sisters are her children, and the children of my father’s brothers are his children, and all are my brothers and sisters. But the children of my mother’s brothers are her nephews and nieces and the children of my father’s sisters are his nephews and nieces, and all are my cousins. The husbands of my mother’s sisters are still her husbands and the wives of my father’s brothers are still his wives, but the sisters of my father and the brothers of my mother are excluded from the family group, and their children are my cousins.[7]
