One example I am a bit more familiar with happens among the Chinese. The Chinese have a strongly maternal orientation. Though often openly in the shadows or serving roles, the mother of the house runs the lives of her husband and children. . . like forever.
Male children - or in the case of mainland China - the one male child has the duty to produce grandchildren for his parents. In the rarer case where there is also a daughter [ recall the law 1 child only] andshe marries and has a child. . .this baby is the grandchild for her nusband's parents, not for her family. The son in the family carries on his father and mother's "memory" and gives them a grandchild[ren] .
