I am looking for any suggestions on place of living of Johann and Charlotte Mordas family. Their daughter Caroline Mordas got married to Matthew Byzio from Czerwonka in Suwalken lutheran church in 1849 (record No. 11). Caroline is reffered to as living with relatives in Czerwonka vilage on russian side, but her parents Johann and deceased Charlotte somwehere in Prussia. If anyone of you have this family in your genealogical tree or any suggestions where to look for, it would be appreciated.
