I love
Gwendolen. In fact,
Gwendolen was one of the names I wanted to change my name to when I was a child (the other was
Bridget). BTW, I love this spelling so much better than
Gwendolyn (maybe because I despise
Lynn and variants). I don't care for
Gwendoline either. I want to pronounce it like
Caroline.
Of your combos, I like:
Gwendolen Audrey Gwendolen Camille Gwendolen CharlottE -- rather than
CharlottaGwendolen JemimaGwendolen Maria Gwendolen Mary Gwendolen MayGwendolen Susanna -- adore this!
Gwendolen Susannah
