My mother-in-laws' family came from Delatyn ,which was in Poland pre WWII, now Ukraine. Her father's name was Jan Sawczuk. She never saw him again after the Nazis captured her, her mother (Rozalia b.1897) and siblings and took them to the work camps. He was on a train ( when his family was captured) and she does not know what happened to him. The family was Roman Catholic. Are there any records such as church, death, etc? Thanks!!
