Looking for a Spanish girls name that can be shortened to Charlie… I don’t like [name_f]Carlota[/name_f] or [name_f]Camila[/name_f], and I’m running low on ideas!
[name_m]Even[/name_m] something that ends in/contains "cha’ might work?
Alternatively, open to other ideas that can be shortened to a cute, gender neutral girls name. (Already have a Frankie) 
Ooh, lovely! I love the name [name_u]Frankie[/name_u], first off, and I love the idea of your post! I’m excited to give these names a try. (PS: [name_u]Frankie[/name_u] and [name_u]Charlie[/name_u] are heavenly sister names!)
For nickname [name_u]Charlie[/name_u] (note that many of these may not be or are not Spanish)…
[name_f]Cambria[/name_f]
[name_f]Carolina[/name_f]
[name_f]Cristabel[/name_f]
[name_f]Christiana[/name_f]
[name_f]Carmelita[/name_f] or [name_f]Carmella[/name_f]
[name_f]Catarina[/name_f]
Camirah
[name_f]Carla[/name_f] or [name_f]Carly[/name_f]
Ceraphina
[name_f]Carrah[/name_f]
[name_f]Cassandra[/name_f]
[name_f]Carina[/name_f]
[name_f]Charity[/name_f] or [name_f]Chastity[/name_f]
For other nicknames…

[name_f]Elisa[/name_f] “Eli”

[name_f]Marcela[/name_f] ‘Charlie’
[name_u]Carmen[/name_u] ‘Charlie’
[name_f]Callista[/name_f] ‘Charlie’
A few other ideas that could have gender neutral nn names:
[name_f]Aurora[/name_f] ‘Rory’
[name_f]Emelina[/name_f] ‘Emil’ ‘Eli’
[name_f]Ignacia[/name_f] ‘Iggy’ ‘Nash’
[name_f]Ingrid[/name_f] ‘Indy’
[name_f]Martina[/name_f] ‘Marty’
[name_f]Noelia[/name_f] ‘Noa’
[name_f]Otilia[/name_f] ‘Otto’
[name_f]Rosalia[/name_f] ‘Rio’ ‘Sal’
[name_f]Serafina[/name_f] ‘Rafi’
[name_f]Aurelia[/name_f] ‘Ray’
[name_f]Antonia[/name_f] ‘Toni’
[name_u]Rosario[/name_u] is commonly shortened to [name_f]Charo[/name_f], which isn’t far off from [name_u]Charlie[/name_u].
[name_f]Sanchia[/name_f]
Thank you so much! Lots of ideas here.
[name_f]Carolina[/name_f] is my suggestion for a Spanish route to [name_u]Charlie[/name_u].
