I like how both names are related to the Moon. You can leave your opinions and suggest another middle name if you like. 😊

Luna means moon

Rays are what ejecta leave behind when meteorites hit the moon’s surface. Also it’s my grandmothers maiden name. (Lol but I like how they two coincidentally fit.)

Rey for a different spelling but it wouldn’t have much significant meaning that way. Maybe only the fact there’s a Rey in Star Wars. I have never watched a single movie though.
