In a story I’m writing, I have two twins who are a prince and a princess. I know I want the boy’s name to be [name_m]Lucian[/name_m], but I need something that sounds elegant and goes well with [name_m]Lucian[/name_m] as the girl’s name. Currently, I’m considering the names [name_f]Estelle[/name_f], [name_f]Aravis[/name_f], and [name_f]Esme[/name_f], but I think I need some different ideas too. Any names would be greatly appreciated! 
I do like the idea of [name_f]Estelle[/name_f], and also
[name_f]Eloise[/name_f]
[name_f]Adele[/name_f]
[name_f]Rosaline[/name_f]
[name_f]Beatrice[/name_f]
[name_f]Lucille[/name_f] or [name_f]Lucinda[/name_f] (Although maybe not with Lucian)
[name_u]Valery[/name_u]
[name_f]Vivienne[/name_f]
Lilith
Daphne
Viola
Siobhan
