Hi Jan,
Zipporah is a very common Jewish name and the english translation is Deborah. Zipporah is in the bible I think in the hebrew bible which is christian Old Testament. And the pp is pronouned like ff and the emphasis is on the ff too. so if you were saying it in hebrew its sounds like......seff-oor-wa. So looks like you got some jewish in there. By the way, I've got a convict ancestor I've yet to trace back to Shrewsbury in Shropshire. Her name was Hannah or Ann Simmons or Simmens.
Regards,
Lisa
