If I saw
Devon on a boy I'd assume it was pronounced "Deh-VAWN" because to me
Devin is the male spelling and
Devon is the female spelling. I could certainly handle
Devon on a boy, (pronounced like
Devin) though. I prefer
Devin all the way around though, even on a girl. Either way I think Devin/Devon sounds dated on a boy, maybe because I grew during the time where
Devon Sawa was like the "it" boy of J-14 and
