[name_m]Hi[/name_m] there.
Here are my thoughts on your list:
[name_u]Eden[/name_u]-For some reason I can’t personally get into this name, but it’s not bad. It fits w/your crew. It’s simple, not too frilly, not over done & grows up well.
[name_f]Juno[/name_f]-I think that this goes really well w/[name_f]Luna[/name_f] & [name_m]Casper[/name_m]. Kind of artsy & just has a similar vibe. Very cute & spunky name.
[name_f]Kitty[/name_f]-So cute! I think that it’s better as a nn though. It’s really fun, different & ready for a comeback. What about [name_f]Katia[/name_f] nn [name_f]Kitty[/name_f]?
[name_f]Lyra[/name_f] - probably too close to [name_f]Luna[/name_f] but it’s always been my favourite name. It was vetoed when naming her.-Yeah, I think too close. Very pretty though.
[name_f]Maia[/name_f]-This is lovely & fits in well. Sort of popular, & really close to [name_f]Mia[/name_f], which is very popular.
[name_u]Nico[/name_u]-This is pretty masculine, in my opinion. I’d love it as a brother to [name_f]Luna[/name_f] & [name_m]Casper[/name_m].
[name_f]Nora[/name_f]-This is a nice solid classic. A little more safe sounding than some of the others, but lovely none the less. I hear it an awful lot in my area if popularity is a concern to you.
Others:
[name_f]Lilith[/name_f]-This is not my favorite [name_f]Lilie[/name_f] name, but it’s kind of cool & different.
Mabli-Ooh, that’s fun & different.
[name_f]Maeve[/name_f]-This is gorgeous. I love the sleek sophisticated feeling of it.
[name_f]Ophelia[/name_f]-This is a little fancy next to [name_f]Luna[/name_f], but it’s fun & different.
[name_f]Rosalie[/name_f]-Aw, so sweet. I love the cheery sound. It’s sort of a different style from [name_f]Luna[/name_f] & [name_m]Casper[/name_m], but it also kind of fits.
[name_f]Saskia[/name_f]-This is not generally my style, but I really kind of like it for you. It’s spunky & feminine w/out being too frilly, just like [name_f]Luna[/name_f].
[name_f]Willow[/name_f]-This is pretty, but I think that I’m getting a little tired of it.
