I really like it actually : ) It would be confused as the word
Guy as a first name unfortunately, but I think you could get away with it. With all of the other unusual and word names I think it could work. It would be cool as a middle name as well though.
Mostly using the usual suspects:
Guy MorpheusGuy Nathaniel /
Nathaniel GuyGuy Edmond /
Edmond GuyGuy PtolemyGuy Ignatius /
Ignatius GuyGuy ClareGuy Crispin /
Crispin GuyGuy Ezra /
Ezra GuyGuy Gerard (Really like this one for some reason)
Guy ConstantineGuy Esmond (
Esmund) /
Esmond GuyGuy Percival
