You had better luck than I. The two parishes, Szebnie and Warczye, split the village of Niepla in the early part of the 20th century. Both parish priests said that all records were sent to the archdiocese, but then again, I didn't have a guy on the ground nor an offering. My info is strictly heresay as I couldn't get a direct response from any of my letters.
If you find anything interesting, please keep me posted.
