In South India, in sharp contrast, marriages are preferred between cousins (especially cross-cousins, that is, the children of a brother and sister) and even between uncles and nieces (especially a man and his elder sister's daughter). The principle involved is that of return--the family that gives a daughter expects one in return, if not now, then in the next generation. The effect of such marriages is to bind people together in relatively small, tight-knit kin groups. A bride moves to her in-laws' home--the home of her grandmother or aunt--and is often comfortable among these familiar faces. Her husband may well be the cousin she has known all her life that she would marry.
