I have found I like a few girl names quite a lot: [name_f]Nicole[/name_f], Nikita, [name_f]Aria[/name_f], [name_f]Octavia[/name_f], [name_f]Elena[/name_f], [name_f]Anastasia[/name_f], [name_f]Katarina[/name_f]. But nothing feels exactly right. The name would go with brothers Tob1as Jam3s and H3nry [name_u]August[/name_u].
As far as style, I typically prefer moderately popular names ([name_u]Noah[/name_u] was in the running for boys, but too high) and longer names for girls. However, I’m open to different things as well.
Thank you for any help!
Some ideas based off the names you like:
[name_f]Nicole[/name_f] - [name_f]Nina[/name_f], [name_f]Caroline[/name_f], [name_f]Matilde[/name_f]
[name_f]Aria[/name_f] - [name_f]Reverie[/name_f], [name_f]Anika[/name_f], [name_f]Anya[/name_f], Aerie
[name_f]Octavia[/name_f] - [name_f]Olympia[/name_f]
[name_f]Elena[/name_f] - [name_f]Irene[/name_f], [name_f]Rowena[/name_f]
[name_f]Anastasia[/name_f] - [name_f]Tatiana[/name_f], [name_f]Sabine[/name_f]
[name_f]Katarina[/name_f] - [name_f]Serena[/name_f], [name_f]Natalia[/name_f], [name_f]Valentina[/name_f]
Some combos:
[name_f]Anya[/name_f] [name_f]Sabine[/name_f]
[name_f]Irene[/name_f] [name_f]Tatiana[/name_f]
[name_f]Nina[/name_f] [name_f]Octavia[/name_f]
[name_f]Caroline[/name_f] [name_f]Aria[/name_f] ‘[name_f]Callie[/name_f]’
[name_f]Rowena[/name_f] Aerie ‘Rowi’
[name_f]Anika[/name_f] [name_f]Matilde[/name_f]

[name_f]Hope[/name_f] this helps. 
Thank you so much for the suggestions! My girl name preferences definitely differ from boys. I like less popular or traditional names, something uniquely elegant without being out there.
Some that have caught my eye: Aerie, [name_f]Olympia[/name_f], [name_f]Anya[/name_f] (love this as a nickname for [name_f]Anastasia[/name_f] and by itself), [name_f]Vera[/name_f].
I really like Aerie so I’m looking into this. But I am also interested in maybe names with the nickname “[name_u]Ari[/name_u]”? I love the idea of calling her [name_u]Ari[/name_u].
[name_f]Arabella[/name_f]
[name_f]Oriana[/name_f]
[name_f]Ariana[/name_f]
[name_f]Aria[/name_f]
[name_f]Ariadne[/name_f]/[name_f]Ariadna[/name_f]
[name_f]Arielle[/name_f]
[name_f]Aurora[/name_f]
[name_f]Aurelia[/name_f]
[name_f]Chiara[/name_f]/[name_f]Kiara[/name_f]
[name_f]Aria[/name_f] is still a favorite. I also like [name_f]Kiara[/name_f]/[name_f]Chiara[/name_f]! Thank you!
Still looking for the one though…
