This just occured to me when he came up in a crossword puzzle. What was Opie short for?
I asked this very Q about 6+ months ago and was referred to an Andy Griffith fan website; search the board and you’ll find the thread with the link.
Apparently Opie was meant to be the kid’s real name. Or if he had another, it was never mentioned in any of the scipts. IIRC, the producers (Sheldon Leonard and Andy Griffith, I think) both admired a depression-era bandleader named Opie something, so they used the name Opie on for Andy’s kid.
It’s possible his “real” name was “Opie.”

Thanks, stuyguy and samclem. This did seem to be the kind of thing that would have been asked before, but I couldn’t find it. Thanks again.
