Post marriage, what normally happens is wife move to husband’s house and changes her surname (called “patrilineal” culture). Well, there is one more culture very few people are aware about – “matrilineal” culture which is opposite to the usual scenario. Under this culture, husband move to wife’s house & changes his surname. Children are also given the surname of mother & generally such children are taken care by their mother’s brother & not their father (strange!). While this culture is not popular in the world (obviously!) but still prevails in some regions of America, Africa, Asia & Oceania. What you think of it?
