Well, I'd have checked the hard-copy but I happen to be working right now and can't get to the library. And no, I'd say that if at least three comprehensive sources come up negative, then either your source is unique (and possibly wrong), or you're lying. Maybe there's a third alternative I haven't seen.

Check it out: Webster's New World Dictionary of the American Language College Edition -- by The World Publishing Company of New York 1966. "Harry .. a masculine name ... n. Satan, the Devil, usually Old Harry". Is that definition in there or not? It is a simple question requiring an honest answer.
