The names are…
[name]Cecilia[/name]
[name]Felicity[/name]
[name]Genevieve[/name] [name]Gigi[/name] or [name]Ginny[/name]
[name]Matilda[/name] [name]Millie[/name] or [name]Tilly[/name]
I am not very big on nick names I like using full names for people unless they tell you that they want to be called by some thing else but I listed the nick names I like best in case on the rare occasion we shortened it.
My favorite is [name]Cecilia[/name]. I’ve always thought this was a beautiful name. Next I like [name]Matilda[/name], then [name]Genevieve[/name], then [name]Felicity[/name].
[name]Cecilia[/name] is my favorite followed by [name]Genevieve[/name]. I don’t really like the other two very much.
I really like all of them! I think my first pick would be [name]Genevieve[/name], followed closely by [name]Matilda[/name] and [name]Cecilia[/name].
[name]Cecilia[/name]- by a landslide. Followed by [name]Matilda[/name].
[name]Matilda[/name] is my favourite. [name]Millie[/name] or [name]Tilly[/name] are both lovely.
I love all of them except [name]Genevieve[/name] (I like it, just not as much)! [name]Cecilia[/name] is very frilly and feminine, [name]Felicity[/name] is proper and buttoned-up, [name]Matilda[/name] is strong and grounded but still feminine. They sound like they could be the names of British nobility. 
I really like [name]Felicity[/name] from your choices! Beautiful name!
You can’t go wrong with any of your choices.
1 [name]Matilda[/name] - majestic and spunky at the same time!
2 [name]Genevieve[/name] - French and romantic.
3 [name]Felicity[/name] - This name makes me smile!
4 [name]Cecilia[/name] - it’s pretty but the meaning of “blind” taints it a bit. I have to get into a more positive frame of mind: St. [name]Cecilia[/name] is the patron saint of music. There now I feel better!
I like all, but [name]Felicity[/name] least and [name]Cecilia[/name] most.
[name]Love[/name] [name]Genevieve[/name]/[name]Gigi[/name]
I like [name]Felicity[/name] the best. I’ve always loved that name
I love, love, love [name]Genevieve[/name]!
[name]Matilda[/name] is the only one I like. If I had to pick [name]Genevieve[/name] would be second, followed by [name]Cecilia[/name]. I really can not stand [name]Felicity[/name].
[name]Genevieve[/name]. I like the nick name [name]Evie[/name].
I really like [name]Felicity[/name] closely followed by [name]Matilda[/name] from your list.
Go with [name]Felicity[/name]. It really doesn’t have any nicknames. I have heard Flis and [name]Flick[/name], but those are a bit odd…not my taste.
[name]Felicity[/name] is so pretty!
I’ll just put them in my order of preference.
[name]Cecilia[/name] is my favorite. I love this name.
