Just came across your query on the message board.
I have hundreds of Nowak's/Novak's and many Czerniak's in my Biadasz Family Tree. All of the ancestoral family originated in the Skarboszewo, Graboszewo, Wierzbocice, and Slupca area. I'm certain that we have a common ancestor.
I can be reached at biadaszw@bellsouth,net I live in Vero Beach, FL
I look forward to hearing from you.
