This is my personal opinion on the names you have considered. I love both names [name_f]Vera[/name_f] and [name_f]Felicity[/name_f]!
[name_f]Maeve[/name_f] ~ [name_u]Love[/name_u] This and think it is lovely with her sisters names
[name_f]Iris[/name_f] ~ Reminds me too much of an eye
[name_f]Marin[/name_f] ~ Sounds very old fashioned to me
[name_u]Simone[/name_u] ~ I don’t usually like names that are female versions of male names and this name also sounds very drawn out and drowsy to me, I don’t like that the name says Moan in it either
[name_f]Laurel[/name_f] ~ Reminds me of the word [name_m]Oral[/name_m], and i wouldn’t want my child to be associated with that word. I love [name_f]Laura[/name_f],[name_u]Laurie[/name_u] and [name_f]Lauren[/name_f] though.
[name_f]Winifred[/name_f] ~ [name_f]Winnie[/name_f] is cute, but i don’t like [name_f]Winifred[/name_f] at all as it sounds old and masculine because of “[name_m]Fred[/name_m]”
[name_f]Dorothea[/name_f] ~ Again [name_f]Dottie[/name_f] is cute but i don’t like [name_f]Dorothea[/name_f], I love [name_f]Thea[/name_f] though.
[name_f]Genevieve[/name_f] ~ This is very pretty
[name_f]Sylvia[/name_f] ~ [name_m]Don[/name_m]'t like this at all and again sounds very old and dated
[name_f]Sylvie[/name_f] ~ Like this name and think it is cute, I don’t think it is too close to [name_f]Vera[/name_f] or [name_f]Felicity[/name_f], I think it matches in nicely as it contains some of the same letters and sounds.
[name_f]Delphine[/name_f] ~ Again sounds too old and dated
[name_f]Josephine[/name_f] ~ Again sounds a little old and i personally wouldn’t use it considering her your husbands name is [name_m]Joseph[/name_m].
[name_f]Hazel[/name_f] ~ This is really pretty and while still being an older name, it does not remind me of an old women. It has the same feel as [name_f]Vera[/name_f] and [name_f]Felicity[/name_f] but it is getting more popular now so i understand why you wouldn’t want to use it.
[name_f]Camille[/name_f] ~ This is pretty and elegant, but she might get called Camel.
[name_f]Imogen[/name_f] ~ This name is really nice and i thing that [name_f]Ginny[/name_f] is a lovely nick name
Dislike: [name_f]Iris[/name_f],[name_f]Marin[/name_f],[name_u]Simone[/name_u],[name_f]Laurel[/name_f],[name_f]Winifred[/name_f],[name_f]Dorothea[/name_f],[name_f]Sylvia[/name_f],[name_f]Delphine[/name_f] and[name_f]Josephine[/name_f].
