[name]Heather[/name] - dated.
[name]Heidi[/name] - it’s okay.
[name]Hilary[/name] - dated.
[name]Hollis[/name] - too surnamey.

[name]Isla[/name] - also nice, but getting too popular.
My favourites are [name]Genevieve[/name] and [name]Gwendolyn[/name].
[name]Felicity[/name] - I like this name
[name]Genevieve[/name] - [name]Lovely[/name]
[name]Greta[/name] - Versatile name that can be a nickname for [name]Margaret[/name] or can stand on its own. [name]Forever[/name] associated for me with Swedish screen actress [name]Greta[/name] [name]Garbo[/name]. I love it!
[name]Gwendolyn[/name] - OK but prefer [name]Guinevere[/name].
[name]Harlow[/name] - Alright but a celebrity baby name which is enough for me to veto
[name]Harper[/name] - Ok but trendy
[name]Hayden[/name] - For a girl? No, leave it for the boys.
[name]Heather[/name] - Stale and outdated
[name]Heidi[/name] - Too cutesy
[name]Hilary[/name] - Ok
[name]Hollis[/name] - [name]Love[/name] this name and also like it spelled Hollace
[name]Imogen[/name] - Very Shakespearean. Like it.
[name]Ireland[/name] - See [name]Harlow[/name]
[name]Isabel[/name] - I like it better than the super popular [name]Isabella[/name] but it’s still too popular to choose
[name]Isla[/name] - Like it
[name]Felicity[/name]- very pretty, especially with the nn Fliss/Flissie
[name]Genevieve[/name]- Absolutely lovely!
[name]Greta[/name]- I prefer it as a spunky nn for [name]Margaret[/name]
[name]Gwendolyn[/name]- Beautiful and elegant. The nn [name]Gwen[/name] is wonderful.
[name]Harlow[/name]- It feels very trendy and celebrity-inspired to me…
[name]Harper[/name]- Not bad but trendy.
[name]Hayden[/name]- It’s too unisex and popular for me.
[name]Heather[/name]- [name]Heather[/name] feels a bit dated but could be potentially refreshing on a little girl.
[name]Heidi[/name]- I think it is a spunky, fresh name that definitely deserves more use.
[name]Hilary[/name]- It feels dated.
[name]Hollis[/name]- The nn [name]Holly[/name] is okay but not my favorite…
[name]Imogen[/name]- I think this is great!
[name]Ireland[/name]- I’m not a fan of place names and this one rings too close to the actual country for my liking.
[name]Isabel[/name]- If popularity is not an issue, I would go for it. If it is, something like [name]Isobel[/name] or [name]Isadora[/name] would be more exotic and less-heard.
[name]Isla[/name]- pretty but apparently is becoming popular at a steady rate.
My favorites are [name]Felicity[/name], [name]Genevieve[/name], [name]Gwendolyn[/name] and [name]Imogen[/name].
Good luck!
