[name_f]Amelie[/name_f] [name_f]Laurel[/name_f] is stunning! What a tough act to follow.
Isabelle/Isobel was my favorite girls’ name for years and years, so I am definitely pro-Isobel, but you don’t sound convinced, so my thought is to keep looking. Same with [name_f]Clara[/name_f].
[name_f]Calla[/name_f] is gorgeous and works great with [name_f]Amelie[/name_f]. Are you in a location with a high Latino population? [name_f]She[/name_f] would get my vote from your list as is, but if the Spanish meaning is insurmountable, I would recommend to keep looking. Would [name_f]Calliope[/name_f] or [name_f]Calista[/name_f] nn [name_f]Calla[/name_f] work a little better potentially?
Regarding [name_f]Nell[/name_f], I do think just [name_f]Nell[/name_f] could work great with [name_f]Amelie[/name_f], but if it feels too diminutive for you, what about [name_f]Helena[/name_f]? [name_f]She[/name_f] feels like a wonderful match for [name_f]Amelie[/name_f] in my head, and easily lends the nn [name_f]Nell[/name_f]! Likewise, I think any -Len- name could work (Milena, [name_f]Marielena[/name_f], [name_f]Lenore[/name_f], etc.?). Or my other thought was something like [name_f]Nadia[/name_f] [name_f]Eloise[/name_f] nn [name_f]Nell[/name_f]. That keeps her from being one of dozens of Ellie’s but also gives you [name_f]Nell[/name_f].
[name_f]Rosalie[/name_f] is beautiful—but if you don’t want to repeat the -lie ending, would another [name_f]Rose[/name_f] name appeal? [name_f]Rosamund[/name_f] was my first idea, but I think [name_f]Rosemary[/name_f], [name_f]Rosalba[/name_f], [name_f]Rosina[/name_f], [name_f]Rosalind[/name_f], [name_f]Primrose[/name_f], etc., could give you [name_f]Rosie[/name_f] or [name_f]Rose[/name_f], and potentially other nns as well (alba for [name_f]Rosalba[/name_f], Sisi/Cece for [name_f]Rosina[/name_f], [name_f]Posy[/name_f] for [name_f]Primrose[/name_f], [name_f]Romy[/name_f] for [name_f]Rosemary[/name_f], [name_f]Rosamund[/name_f], or Primrose?).
