I’ve been drawn to the moon and people with moon related second names (Moon, Selene, Luna) without knowing as a form of synchronicity way before my witchy awakening… We consider each other sisters with my very first partner now, who’s come to use Moon as a last name, so… I’m honoring that connection by having the same last name as a magickal name! 
My second name is Celestia, and I think Celestia Moon would sound beautiful and meaningful… maybe a little grandiose but that’s not necessarily a bad thing? I’ve been waiting for a nudge of synchronicity or something to pick it up, maybe this could be it…
