I love it!
June is one of my go-to middle names - every first name I consider gets hypothetically paired with it. I think it works beautifully with Zaelia.
A few names with "
Loren" sounds come to mind; Zaelia
Florence (if you don't mind too many flower meanings); Zaelia
Lorenza (if you think an L and a Z in both names is alright, plus the close proximity of the L's. Personally, I don't mind it in this case.)
Or how about... Zaelia
Magdalen?
I'll leave it at that for now.
