Sally, I don't know very much about this line. I've been seeking clues for many years. I would like to find where he is buried. His daughter Maggie Graham McKnight m. Edward McKnight. They had a daughter Margaret McKnight ( my grandmother). Maggie Graham McKnight died when my grandmother was young. Her father left. She stayed with her grandmother (Andrew Graham's wife) until she lost her sight. My grandmother told me she was about 11 or 12 at this time, I think. At that time she went to work for a family in Dolton, Cook County, IL. She remained close to this family all her life. My grandmother was Methodist but this could have been because the family that raised her was that religion. Do you know where your Thomas Graham is buried? What year did he come over from Ireland? Have you found him on any ship passenger list?
