Thank you for the wonderful advice, ladies. Please keep it coming! :)
ashthedreamer - I love the suggestion of Arianne, haven't considered that before!
Ariana/Arianna is definitely my least favorite (and when you combine the two spellings it's more popular that #14 Addison, if that means anything to you).
My vote goes to Imogen. I don't know where you're from, but in the U.S. you'd have some pronunciation problems. Imogen is unusual here - most people who aren't name nerds haven't heard of it and many who have would think of it as exclusively British - but if you can get past those issues, it's a quirky yet classic name.
The charming Eloise is my second pick.
Gretal - how would Americans pronounce it, a few people on here have said the same to this name? I'm English but now live in Australia with my Australian husband. I only know of the one way of pronouncing the name. I find international variations of names fascinating.
Thanks for your opinions also :)
And there might be confusion over where the stress/emphasis goes.
Oh I see, I've never really thought of other ways to pronounce. Thanks for sharing! :)
