I like Crispin, what of it? Wouldn't use it though, as went to uni with a Crispin who was a neurotic, sexually-confused ginger vegan who was also the best friend of an ex who must only be referred to as The Evil One no. 2 (sadly, there is a no.1).
Sadly, my picks make your suggestions sound butch and manly: Lysander, Orlando, Florian, Fabian... you name it!
Disclaimer: obviously, I wouldn't use any of those names. Me and TYF also really like mythical names, but as much as we might like Persephone, etc., we just wouldn't inflict it on a child.
The real problem with names is you never know if they'll start out fine and then become associated with something culturally crappy. My name is the coolest in the world but 1 year after I was born, someone with the same name became incredibly famous and a bit of a comic target and I was teased day in, day out cos of it. Still LOVE my name, though, even if still get the same comments occasionally. TYF's name was v unusual when he was born but it's become popular now and quite a few slebs have called their kids it (including a v chavvy one) and that drives him mad. You just gotta use good sense and taste and hope for the best
I bet 95% of people here have a Mum with one of the following names: Ann(e), Mary, Margaret, Pat/Trisha, Pamela, Susan, Christine, Barbara, Maureen, Sheila, Sylvia, Jane, Jean, Cath/Kath, etc.! My own dear Mama has 2 of 'em!
