Even if it's just my internet alter-ego :)
After using it as such for several years now, it's actually grown on me as a real name. It's a girl's name to me, but then I'm not American so
Blythe, along with
Meryl,
Alison and
Marion are all female.
My favourites are
Marion Blythe,
Margot Blythe and
Margaret Blythe,
Frances Blythe and
Roberta Blythe.
