Did Carol list any children for George? My great grandfather was a George Kestler who had a brother William and possibly other siblings. My mother doesn't remember her father very much, he died when she was 6,and her grandfather died when her father, Joseph Kestler, was young. She knows George had a younger brother William who lived in Sullivan County New York and Pennsylvania. I have very little information on this family, most of it came from my grandfather's very limited Social Security application.
