I pretty sure those are the only churchbook records to survive for Wittenfelde-Stuchow because they were a duplicate and were in the archive in Greifenberg during WWII and not in the parish. So, chances are there aren't any more records to research, unfortunately. Some of the towns I would like to look at have nothing, all have been lost or destroyed during the war or shortly after the expulsion of Germans from Hinterpommern. Many of the original churchbooks didn't survive. some say less than 20% throughout Pomerania.
