I don't actually know of a specific
Blake on a specific soap opera, but I just hear soap opera when I think of the name
Blake. Which is not a great association.
I'd say
Peyton is pretty fair game for either sex. It's recently more popular on girls than boys, but it's certainly not unheard of on boys either. That said, I have a son named
Emerson and wouldn't hesitate to use
Rowan and
Morgan on boys either, so I may be biased.
