AMAR means "to love" in Portuguese. Bearing in mind that India suffered from Portuguese influence in the 15th/16th century maybe it should be considered. Well, love is immortal so I guess it's fine. lol
There is a character in The Gemma Doyle Trilogy (written by Libba Bray) named Amar. He was killed in the first book and has become a partially corrupted soul by the third, but his brother kills him at his own request once and for all.
