I discovered a bit of family lore that says a great-aunt was married to the son of the Chief Rabbi of Vienna. The son was named Josef KATZ, and he was a schoichet. They lived in Skala Podolskaya and later moved to the Czernowitz region of Bukowina. Would anyone be able to tell me how I can find out who the Chief Rabbi of Vienna was in the late 1800s? I posted this to the RavSig group but got no responses.
