I just want something short and sweet that fits well with [name]Emma[/name] and [name]Evie[/name]…
[name]Emma[/name] [name]Gail[/name]
[name]Evie[/name] Frenchy
Unless you want to set the pattern of using all E names, I would go with a new first letter. I think another vowel would be smashing, but included others starting with consonants. [name]Emma[/name], [name]Evie[/name], and…
[name]Alice[/name]
[name]April[/name]
[name]Audrey[/name]
[name]Isla[/name]
[name]Iris[/name]
[name]Olive[/name] or just [name]Liv[/name]
[name]Claire[/name] or [name]Clara[/name]
[name]Liza[/name]
[name]Tess[/name] or [name]Tessa[/name]
[name]Jane[/name] or [name]June[/name]
[name]Linnet[/name]
[name]Lucy[/name]
[name]Lane[/name]/[name]Laine[/name]
[name]Chloe[/name] or [name]Cleo[/name]/[name]Clio[/name]
[name]How[/name] about [name]Elle[/name]?
U could always go with [name]Ella[/name] or [name]Ellie[/name] but I think those might be too close to the names of your first two.
E names in case you want to continue that theme:
[name]Eliza[/name]
[name]Elise[/name]
[name]Elsa[/name]
[name]Erica[/name]/[name]Erin[/name] - too dated?
Other short and sweet:
[name]Chloe[/name]
[name]Grace[/name]
[name]Shea[/name]/[name]Shay[/name]
[name]Nora[/name]
[name]Neve[/name]
[name]Nola[/name]
[name]Mila[/name]
[name]Maisie[/name]
[name]Tess[/name]
[name]Lucy[/name]
[name]Lacey[/name]
[name]Liv[/name]
[name]Hannah[/name]
[name]Lily[/name]
[name]Rose[/name]
[name]Sophie[/name]
[name]Molly[/name]
I think [name]Clara[/name] or [name]Claire[/name] go great.
more ideas-
[name]Eden[/name]
[name]Lara[/name]

[name]Ruby[/name]
[name]Cora[/name]
[name]Betsy[/name]

I have a similar quest. I am trying to find a girl name with siblings [name]Dylan[/name] [name]Daniel[/name] and [name]Eve[/name] [name]Sofia[/name]. I am thinking [name]Elise[/name], [name]Greta[/name], [name]Livia[/name], [name]Penelope[/name] nickname [name]Pia[/name], [name]Rose[/name] even though dh said [name]Rosalie[/name], [name]Violet[/name], [name]Cara[/name], [name]Gemma[/name], [name]Charlotte[/name], [name]Matilda[/name] nn [name]Tillie[/name], [name]Maisie[/name], [name]Vera[/name] but [name]Vera[/name] Wang and [name]Vera[/name] [name]Bradley[/name] kinda ruin it, [name]Chloe[/name] but seems too common now, I would pick [name]Emma[/name] in an flash but had a cat named [name]Emma[/name] 
so dh said no. I also like [name]Piper[/name] but had a dog named [name]Piper[/name]. I like [name]Stella[/name] but dh said no way due to name associations if knowing someone…
I think [name]Evie[/name] [name]Emma[/name] and [name]Rose[/name] are pretty. Oh how about [name]Sophie[/name]? I love [name]Sophie[/name] and would use it but its too similar to my dd mn [name]Sofia[/name].
[name]Evie[/name] [name]Emma[/name] and [name]Sophie[/name]- perfect!
I like [name]Sophie[/name]!
tifberry - we just had a [name]Rose[/name] born in our group of Friends
Maybe [name]Eliza[/name]??
For some reason I feel like I need to stick with an E…
[name]Emma[/name], [name]Evie[/name], and [name]Elle[/name] are my favorite set sticking with “E”
[name]Emma[/name], [name]Evie[/name], and [name]Elise[/name] are sweet too. I like the idea of all three names having a different consonant after the E and a different ending.
Others that fit that…
[name]Esme[/name]
[name]Estelle[/name]
[name]Esther[/name]
