[name_f]Elvire[/name_f], [name_u]French[/name_u] version of [name_f]Elvira[/name_f]
[name_f]Elvie[/name_f]
[name_m]Elven[/name_m] maybe?
Elvan is a unisex Turkish name meaning “colors”
[name_f]My[/name_f] favorites are [name_f]Elva[/name_f] and [name_f]Elvia[/name_f]
I really like [name_f]Elvi[/name_f] or [name_f]Elvie[/name_f] as a nickname for [name_f]Lavender[/name_f], but it could definitely stand on its own too.
I had aunts somewhere back in the family tree called [name_f]Elvira[/name_f] and [name_f]Edwina[/name_f] and I always thought that was a cool matchy sibset
I really like [name_f]Elvira[/name_f], [name_f]Elvie[/name_f] and [name_f]Elva[/name_f], but unfortunately I’d never be able to use them due to family reasons.
Some others:
Elviana
Elvinnea
[name_f]Elvinia[/name_f]
I like [name_f]Elva[/name_f] and [name_f]Elvira[/name_f] just like you. Almost was fond of [name_f]Elvina[/name_f] too but I think it sounds far too generic.
