Where there are several sisters of a family, they are all regarded as the wives of the man who marries the eldest of them. He may, if he chooses, waive his right in favor of his younger brother, with the consent of the father of the girls. If a family contained four girls and a man took the two eldest, but permitted his younger brother to marry the third, the youngest daughter thereby also becomes the wife of the younger brother, and the older brother cannot claim any right to her. When a man dies his wives pass to his younger brother or to the man who stands nearest to him in the relation of margara [younger cousin]. This man marries the widow and adopts the children.2
