Theodora Hilda Blythe gets my vote.
Daphne reminds me too much of Scooby Doo, and it seems empty somehow. I love
Winifred, but I like it more in the middle name slot. I think it's a bit too frumpy as a first name and it's extra frump with
Hilda.
I love love love
Theodora. I think it has a lot of life, while still being classic. Plus, loads of nickname potential if you are into that!
