I’ll just talk about my favorites from your lists:
[name_u]Everly[/name_u] [name_f]Diana[/name_f] - I really like this one. For such a modern name as [name_u]Everly[/name_u], [name_f]Diana[/name_f] is the perfect middle name – classic and strong, it really grounds the more whimsical [name_u]Everly[/name_u].
[name_f]Belle[/name_f] [name_f]Fiora[/name_f] - Sounds like a fairy tale name, and I love it!
[name_f]Eve[/name_f] Romilia - Gorgeous. I’ve always loved Romilia, but nobody else seems to even know it exists. I love seeing it used so perfectly.
[name_f]Gia[/name_f] [name_f]Rose[/name_f] [name_f]Renata[/name_f] - Something about the sound of this one is great! I really like these names together, and it sounds really sweet and fun as a whole.
[name_f]Audrey[/name_f] [name_f]Elise[/name_f] - [name_m]Just[/name_m] so classy!
