I'm an
Oscar Wilde fan and Vyvyan was the name of his son.
I quite like it. I don't usually like off-kilter spellings, but that one just looks so cool and it has history, so I feel my liking it is somewhat justified.
On a terrible note, I met twins named
Ashlyn and
Aislin once. The parents were pronouncing it AYEZ-lyn. Seriously.
