I usually prefer [name_f]Zoey[/name_f], but with your boys [name_u]Aspen[/name_u] works super well!
I love [name_f]Zoey[/name_f]! (Spelled this way with the y!) And [name_f]Zoey[/name_f] [name_f]Elizabeth[/name_f] is just the right mix of spunky and elegant.
Some more ideas…
[name_f]Astrid[/name_f]
[name_f]Ava[/name_f]
[name_f]Athena[/name_f]
[name_f]Summer[/name_f]
[name_u]Shiloh[/name_u]
[name_u]Piper[/name_u]
[name_u]Harper[/name_u]
[name_u]Nova[/name_u]
[name_u]Aspen[/name_u] sounds like the perfect choice for your family
Really like [name_u]Aspen[/name_u] over [name_f]Zoey[/name_f]. Maybe [name_u]Aster[/name_u]?
I like [name_u]Aspen[/name_u]–and I can only assume it has some personal significance for you. But I’m also partial to the idea of your girl not having the same -n suffix as the boys. Could she be [name_u]Aspen[/name_u], nn [name_u]Penny[/name_u]???
