Claudia by far!
Claudia is a hidden treasure in my opinion. I think you should go with that.
Pacifica: Thanks for all the suggestions! I like Pamela Briony, Pamela Iris, and your idea of Hesper, reminded me of Vesper which has special meaning to me, so I like Pamela Vesper too! I also like Claudia Penelope, Willow, Jane and Elowen.
axps: I love Pamela Violet/Clover too! Thanks!
Juniperle: I like Claudia Jane too! And Jane is a family name that I have to use, but I wasn't sure if it fit.
Everyone: Thanks for everything. Any more middle name ideas?
