Congrats! 
My faves
[name_f]Beatrix[/name_f] - would be my pick
[name_f]Ariadne[/name_f]
[name_f]Zinnia[/name_f] - I think [name_f]Zinnia[/name_f] [name_f]Pearl[/name_f] could be lovely
[name_f]Matilda[/name_f]
[name_f]Allegra[/name_f]
[name_f]Guinevere[/name_f]
Ones I like but wouldn’t be what I’d choose over the other choices
[name_f]Daphne[/name_f] - like it and agree it suits - but not as sparkly to me these days
[name_f]Penelope[/name_f] - doesn’t age as well somehow (imo)
[name_f]Clementine[/name_f] - actually really like, just think try for a non C name first as [name_f]Duffy[/name_f] after [name_f]Cordelia[/name_f]
[name_f]Athena[/name_f] - prefer other TH names
[name_m]Not[/name_m] as keen on
[name_f]Calliope[/name_f] - wouldn’t have a C name right after [name_f]Cordelia[/name_f] and I’m not a [name_f]Callie[/name_f] fan
[name_f]Dahlia[/name_f] - just don’t like the sound esp the Darl-ya pronunciation and doesn’t work after [name_f]Cordelia[/name_f]
[name_f]Octavia[/name_f] - for reasons above (but could use [name_f]Octavia[/name_f] June), same for [name_f]Olive[/name_f] (maybe [name_f]Olive[/name_f] in second spot?)
[name_f]Aurelia[/name_f] - not straight after [name_f]Cordelia[/name_f] - too rhyming
[name_f]Ivy[/name_f] - like the name, just sinks a little with the other two. Maybe a middle instead.
[name_f]Juniper[/name_f] - too gender neutral and different to the pretty and dramatic [name_f]Cordelia[/name_f] - could do [name_f]Juliet[/name_f] [name_f]Delphine[/name_f] nn [name_f]Juno[/name_f] instead?
