I like the sound of
Eden and I love the possible nn
Edie. But the overall association I have with
Eden is the obvious Biblical one. It just sounds like a soap opera character, and a trampy one at that. Sorry. How about
Enid or
Emer?
I like the sound of
Imogen too. The overall association I have with it is much more positive. The obvious Shakespeare reference is the cherry on top of the name for me. Plus, I have a thing for feminine "i" names.
Imogen?
Love, love, love it -- from all angles.
