I’ve starred those we would use in a heartbeat.
They’ve probably all been named, but my favorites include [name_f]Cassia[/name_f] (I pronounce it CAH-shuh, but I like [name_u]CASS[/name_u]-ee-uh too), [name_f]Calla[/name_f], [name_f]Cora[/name_f], [name_f]Cordelia[/name_f], [name_f]Coraline[/name_f], [name_f]Caroline[/name_f], [name_f]Cleo[/name_f], [name_f]Calista[/name_f], [name_f]Colette[/name_f], [name_f]Camila[/name_f]/[name_f]Camilla[/name_f] (obv. out for you).
I see you have [name_f]Coraline[/name_f] on your list, as well as [name_f]Sylvia[/name_f] in your sig-- [name_f]Sylvie[/name_f] [name_f]Coraline[/name_f] is one of my top names for a daughter! I love it (love [name_f]Mila[/name_f] and [name_u]Cato[/name_u] too which are both also high on my list!). Not sure if you like [name_f]Sylvie[/name_f] vs. [name_f]Sylvia[/name_f], but I think it would be a great fit. [name_f]Sylvie[/name_f] [name_f]Colette[/name_f] is another good one.
