[name_f]Nicolette[/name_f]
[name_f]Cosette[/name_f]
[name_f]Colette[/name_f]
[name_f]Gemma[/name_f]

[name_f]Stella[/name_f]
[name_f]Helena[/name_f]
[name_f]Leanna[/name_f]
[name_f]Rhiannon[/name_f]
[name_f]Rosamund[/name_f]
[name_f]Freya[/name_f]
[name_f]Christiana[/name_f]

[name_f]Sonia[/name_f]/[name_f]Sonya[/name_f]
[name_f]Evangeline[/name_f]
[name_f]Bellatrix[/name_f]
Belladonna
[name_f]Isabeau[/name_f]
[name_f]Esperanza[/name_f] comes to my mind.
[name_f]Adele[/name_f] was my first idea. Other than that, I love the suggestion of [name_f]Beatrix[/name_f]. [name_f]Estelle[/name_f] also comes to mind. [name_f]Alice[/name_f]? [name_f]Ariana[/name_f]? Or even [name_f]Aurelia[/name_f], [name_f]Ariane[/name_f], [name_f]Sylvie[/name_f], [name_f]Georgiana[/name_f]/[name_f]Georgia[/name_f]/[name_f]Georgina[/name_f], [name_f]Helene[/name_f] (which strikes me as extremely regal-sounding, although I don’t know if royalty really uses it. In [name_m]French[/name_m] it’s ay-[name_m]LEN[/name_m] and in Danish it’s heh-[name_m]LAY[/name_m]-nah. I adore both.), [name_f]Caroline[/name_f] (I think the [name_m]French[/name_m] pronunciation, care-oh-leen, sounds more regal than the English/American care-oh-line), [name_f]Eveline[/name_f]/[name_f]Evelina[/name_f].
Good luck!
Nikolaevna
[name_f]Regina[/name_f] (reh-gee-nah)
The latest name on our list: [name_f]Teodora[/name_f].
I would second pretty much all of these. Some that haven’t been mentioned I don’t think;
[name_f]Sybilla[/name_f]
[name_f]Perdita[/name_f]
[name_f]Leonor[/name_f]
[name_f]Lovisa[/name_f]
[name_f]Solveig[/name_f]
Anaheed
[name_f]Arbella[/name_f]
[name_f]Raphaela[/name_f]
[name_f]Sabine[/name_f]
[name_f]Victrice[/name_f]
[name_f]Esmeralda[/name_f]
[name_f]Sofia[/name_f]
[name_f]Titania[/name_f]
[name_f]Vittoria[/name_f]
[name_f]Margarethe[/name_f]
They all feel like obscure European royalty to me.

Some of these names are from old princesses irl, others are just ones I thought of. I notice a lot of names I find regal/princessy end with a, the (uh) sound. Hope these helped. And sorry the list is so long… LOL.
Dang it! I was going to say [name_f]Regina[/name_f] but someone beat me to it.
