I adore [name]Etta[/name], and [name]Cora[/name], but I think they need to be nn’s for something, even if the full name is never used (like [name]Henrietta[/name] and [name]Cordelia[/name], even though I actually am not fond of either of those).
Oh I love [name]Sylvie[/name]! I actually don’t mind [name]Sylvia[/name] either. It sounds so perfectly soft and feminine when you say it aloud. Other names that you’d think would be more popular…[name]Ada[/name], [name]Viola[/name], [name]Iris[/name], [name]Maisie[/name].
