I grew up with an annoying boy named
Raymond, and I've known more than a few Raymonds that went by
Ray that were less than stellar gentlemen. :-/ But I also know a sweet little boy named
Raymond now, and it was also the name of a sweet elderly man I knew. I like it, but I'm not crazy about
Ray (though it's growing on me more, thanks to Array :b).
Raymond John isn't bad--actually the little boy I know, his little brother is
John nn Jack--but I'm not crazy about
John as a mn in general. It sounds out of place and abrupt to me for some reason (maybe because it's so common as a fn?).
