I can help there. It's not a shortened form of
Joseph as such but an elaboration of Jo/Joe via
Joey with the D added for euphony. Sort of like
Maire to Maile/Mary to
Molly or Sarah/Sarie/Sadie.
It's link to Jude/Judith is highly uncertain and no explanation for the switch of vowels has ever been put forth. Given the relative traditional obscurity of Jude/Judith compared with Joseph/Josephine/Joanna/etc. it's actually not as likely. But the myriad meanings of
Joe- shortened names makes them a pain - could be '(God) shall add', 'dove', 'flowing down', 'God is salvation', 'God heals', etc. Pointing boy
Jody's to
Jude and girl
Jody's to
Judith is a thousand times easier! I can't go back in time and watch it happen but I'd put my money on
Jody for a boy coming from
Joey '(God) shall add' and for a girl from
Joanna ('God is gracious') or
Josephine (same as Joseph/Joey).
But never 'playful'....out of curiousity, where did that idea come from?
