Re: Hinduism ?
read properly again,i said cross cousin marriage,since opposite sibling are given to another family they will have gotra of husband’s family
about mama marriage it’s very rare nowadays,in olden days* defference between first and last child would be like 20 plus years,they use to bare childerns until age of 50
lolz in some cases mama would be younger then her niece,even then these people will belong to defferent families, since mother is married to another family*
