Aénor is a beautiful name.I know that it is the origin of another name (Aliénor) that means 'The other Aénor'.Being linked with a Duchess mother of a Queen this name has a lovely Medieval and royal vibe but its sound is also very similar to some fantasy names like the Elves of Tolkien or the Valyrian names of ASOIAF. Both are good associations in my opinion.I've never seen it in real life but it is wonderful!I pronounce it a-AY-nawr with 'ay' like the French é and a closed 'o'.
