Feyre- cool for a character, cool meaning, but it’s not my style
Clarissa- not really a fan? It’s just a bit boring and reminds me of the girl from
Percy Jackson.
Cassandra is better because at least it sounds fancy.
Ælfwynn- I’d only name an elf this. I don’t think it’s good even by 12th century standards, there are much cooler names from that time.
