Fern- Nice as a mn- I would love the sound of Lydia Fern!
Fauna- Okay. A little too cutesy, but could be lovely in the middle.
Fay- Love the meaning of this!
Claudia- Lovely name, bad meaning.
Linnea- Gorgeous! Love Linnea.
Bette- How would you pronounce this? I think BET-ee has more personality.
Cleo- LOVE LOVE LOVE this!
Olympia- Pretty! I like this a lot.
Teal- Maybe in the middle.
Vera- Beautiful, of course!
Zelda- Too attached to the character, for me.

I really like Fern.
I like Dawn too! The dated aspect doesn't bother me...but the cleaning products give me pause!
