So that her children will be genetically/socially identical to any children she would have had with her first husband, and have the same social identity, clan membership, marital options, etc. and so that she will not become a sexual threat to the relationships of other women in the tribe (her sexual needs being recognised and provided for). Indicative of a matrilineal kinship system. Compare with similar rules in ancient Judaism and the Niyoga pattern of second marriages to brothers in traditional Kerala castes.

Of course you could. But you're implying to incest and this is definitely not incest.
The English word uncle unfortunately does not differentiate between father's brother and mother's (usually younger)brother. Both are uncles! A tamil girl would marry her mother's brother - uncle. A mother's brother is called மாமன் (maaman)
If both are christians I think there is no problem. They are not blood relatives the only relationship they have is through your marriage
If you are a woman, and your grandmother's brother is a great deal younger than your grandmother, or a little younger and had a son very late in life, then you could marry him legally in many, but not all, parts of the world. You and he are first cousins, once removed.
