[name]Calliope[/name] ([name]Cal[/name]-EYE-oh-pee)
[name]Felicity[/name]
[name]Isobel[/name] (I no its popular but if I use it in a few years then maybe it won’t be)
[name]Arizona[/name] (Yes a place name, but I dunno I just like this one)
[name]Imogen[/name] ([name]Kinda[/name] popular though)
[name]Beatrix[/name]
[name]Pandora[/name] (chavy maybe?)
[name]Arizona[/name], [name]Isobel[/name][ & [name]Calliope[/name], are we a [name]Grey[/name]'s Anatomy fan? I think [name]Beatrix[/name] is a interesting name, I wouldn’t particulary use any of the names on your list but out of your list if I did It would be [name]Arizona[/name].
[name]Calliope[/name] - Not a fan. I just think of the instrument.
[name]Felicity[/name] - [name]Love[/name] [name]Felicity[/name]. Beautiful name and I love that it means “happy”.
[name]Isobel[/name] - [name]Love[/name] [name]Isobel[/name]. Popularity doesn’t really bother me, especially when you’re considering a classic name like [name]Isobel[/name].
[name]Arizona[/name] - [name]Just[/name] a state to me. Can’t see this as a name.
[name]Imogen[/name] - [name]Love[/name] this one too. Very pretty.
[name]Beatrix[/name] - Also love this one, especially with the nickname [name]Trixie[/name].
[name]Pandora[/name] - For some reason, despite the mythology, [name]Pandora[/name] always sounds like a stripper name to me. I don’t know why.
I really like [name]Beatrix[/name] from your list.
I love [name]Isobel[/name] with this spelling. I also adore [name]Imogen[/name] - are you in the U.K.? Because it’s definitely not popular in the U.S.
1 [name]Felicity[/name] - I love a lot about this name: it’s wonderful meaning, it’s happy sound and its joyful spirit.
2 [name]Isobel[/name] - My preferred spelling is [name]Isabel[/name] but this Scottish spelling is second. Very pretty.
3 [name]Beatrix[/name] - [name]Love[/name] the literary association with Ms [name]Potter[/name].
4 [name]Calliope[/name] - A spunky mythological name.
5 [name]Imogen[/name] - I used to like this name but my love has diminished.
6 [name]Pandora[/name] - I wouldn’t use due to the negative mythological story as well as the jewellery brand name
7 [name]Arizona[/name] - it’s ok but there is a model named [name]Arizona[/name] [name]Muse[/name] whom I’ve seen in magazines lately.
[name]Calliope[/name] - [name]Love[/name]!
[name]Felicity[/name] - Like, very pretty.
[name]Isobel[/name] - Prefer [name]Isabel[/name], but it’s fine. Overused though.
[name]Arizona[/name] - Not a fan.
[name]Imogen[/name] - Well, it’s definitely not popular in the US (not in top 1000) but I don’t know where you live. I like it.
[name]Beatrix[/name] - [name]Don[/name]'t like at all.
[name]Pandora[/name] - Too connected to the mythology and the internet radio, I wouldn’t use it.
[name]Calliope[/name] - too out-there for me, but I do love the nn [name]Callie[/name] and I think it is gorgeous. A few years ago it was on my long list, before I realized I’d never use it.
[name]Felicity[/name] - gorgeous. Something always holds me back, but it’s so dainty and sweet and I really do love it.
[name]Isobel[/name] - I prefer [name]Isabelle[/name]. No matter how it’s spelled, though, I really adore it.
[name]Arizona[/name] - again, too GPish for me. I do love the nn [name]Ari[/name], but I would use [name]Arianne[/name], [name]Ariana[/name], [name]Aurora[/name], [name]Aurelia[/name]/[name]Aurelie[/name], [name]Arielle[/name]/a, [name]Arabella[/name], etc. as ways to get to it.
[name]Imogen[/name] - I agree, it’s practically unheard of in the US, but if you’re in the UK or Australia, I could see your concern. It is lovely, though. 
[name]Beatrix[/name] - love. So much spunkier than [name]Beatrice[/name], which I see the appeal of but don’t love. I wouldn’t use [name]Beatrix[/name] as a FN, but I love it for a MN.
[name]Pandora[/name] - I love its sound and image, it’s just so rich and sweet, but the stigma surrounding it keeps me from using it.
I love [name]Felicity[/name], [name]Beatrix[/name] and [name]Pandora[/name]. I’ve started associating the word adorable with [name]Pandora[/name].
I dislike them all /-: not my style. I can see the appeal to them all, though!
