You haven’t really said much about your character. Is she old or young? Where dies she live? What is he [name_m]King[/name_m] [name_m]Arthur[/name_m] equivalent?
But stil, [name_f]Twyla[/name_f]/[name_f]Twila[/name_f] might wok.

[name_f]Do[/name_f] you want Arthurian inspired names?

[name_m]Merlin[/name_m] > [name_f]Marlene[/name_f], [name_f]Mary[/name_f]-[name_u]Lynn[/name_u] or anything with a [name_u]Lyn[/name_u] ending would work

[name_f]Guinivere[/name_f] > [name_f]Gwenyth[/name_f], [name_f]Evie[/name_f] (from the -evere bit), [name_f]Vera[/name_f] (ditto), [name_f]Winnie[/name_f]

[name_f]Margret[/name_f], [name_f]Vernia[/name_f], [name_f]Aurore[/name_f], [name_f]Thyra[/name_f], [name_f]Odette[/name_f], [name_f]Rhea[/name_f], [name_f]Clemence[/name_f], [name_u]Dagny[/name_u], [name_f]Leonor[/name_f], [name_f]Geneva[/name_f], [name_f]Electa[/name_f], [name_f]Mair[/name_f], [name_m]Byrne[/name_m]
