The last rule, it is said, also applies to the maternal aunt.

The Kunbis, and other Maratha castes, have a saying: 'At the sister's house the brother's daughter is a daughter-in-law.' The Gonds call the wedding of a brother's daughter to a sister's son _Dudh lautana_, or 'bringing back the milk.' The reason why a brother was formerly anxious to marry his daughter to his sister's son was that the latter would be his heir under the matriarchal system; but now that inheritance is through males, and girls are at a premium for marriage, a brother is usually more anxious to get his sister's daughter for his son, and on the analogy of the opposite union it is sometimes supposed, as among the Gonds, that he also has a right to her.

Many other instances of the special relation between a brother and his sister's children are given by Sir J.G.Frazer in _Totemism and Exogamy_.

In some localities also the Korkus build their villages in two long lines of houses on each side of the road, and it may be the case that this is a relic of the period when two or more clans with female descent lived in the same village, and those belonging to each class who could not marry or have sexual relations among themselves occupied one side of the road.

The transfer of the reckoning of kinship and descent from the mother's to the father's side may perhaps be associated with the full recognition of the physical fact of paternity.
