Daughters are Eliana (nn: Ella/ Elle), Adeline (nn: Addie/ Ade)… struggling with a third girl name that has a similar vibe and flow.
Current list:
Eliza (nn: Izzy)
Emelia (nn: Emmy)
Cecelia (nn: Cece)
none of these feel quite right but I don’t know why.
I also love Evelyn but husband is a firm no.
Please help add to my list!
Maybe you’ll like
[name_f]Cecily[/name_f]
[name_u]Florence[/name_u]
[name_f]Celia[/name_f]
[name_f]Cordelia[/name_f]
[name_f]Ophelia[/name_f]
[name_f]Beatrice[/name_f]
[name_f]Louisa[/name_f]
[name_u]Louise[/name_u]
[name_f]Theodora[/name_f]
Good luck!
[name_f]Cecilia[/name_f] is probably the best choice.
I suggest [name_f]Linley[/name_f], [name_f]Lillian[/name_f], or [name_f]Leilia[/name_f]
I think [name_f]Emelia[/name_f] (or Emilia?) fits the best with your girls!
[name_f]Camila[/name_f]
[name_f]Natalia[/name_f]
[name_f]Valeria[/name_f]
[name_f]Nadia[/name_f]
[name_f]Sofia[/name_f]
[name_f]Olivia[/name_f]
[name_f]Selena[/name_f]
[name_f]Sophie[/name_f]
[name_f]Serena[/name_f]

[name_f]Aliyah[/name_f]
[name_f]Karina[/name_f]
[name_f]Marisa[/name_f]
[name_f]Francesca[/name_f]
what about isabel or isadora as a full name for izzy? i like them better w eliana and adelina.
other ideas:
juliet
arabella
everly
evangeline (like evelyn?)
cecily (i also love cecilia)
amelia
emmeline or emilia/emelia
audrey
eleanor
annie/anna
allison
clara
brielle (though the ending might be too close to eliana/elle)
lucille
frances
bianca
daphne
felicity (might be a stretch but could work as a fn for izzy)
matilda
hope this helps!!
[name_m]Hi[/name_m] there.
[name_f]Eliana[/name_f] & [name_f]Adeline[/name_f] are lovely.
How about…
[name_f]Abigail[/name_f]
[name_f]Alice[/name_f]
[name_f]Celia[/name_f]
[name_f]Eve[/name_f]
[name_f]Eva[/name_f]
[name_f]Isabel[/name_f]
[name_f]Josephine[/name_f]
[name_f]Lucia[/name_f]

[name_f]Hope[/name_f] this helps. 
[name_f]Eliza[/name_f] and [name_f]Emilia[/name_f] feel too close to [name_f]Eliana[/name_f]. I like how [name_f]Cecelia[/name_f] has a similar feel, ties all the names together with the “L” sound, and has a distinct nickname. I also like [name_f]Olivia[/name_f] with your sibset
[name_f]Eliza[/name_f] feels very similar to [name_f]Eliana[/name_f], but [name_f]Emelia[/name_f] and [name_f]Cecelia[/name_f] would both work really well in my opinon.
