My grandmother's maternal grandparents, James Scott and his second wife, Ruthie Ramson reared her until she was 10-11 years old. Her mother remarried Jim Morgan, a Baptist minister, and they lived in Paducah and Bardwell until 1880, when they moved to Cohn County, Texas and took the children with them. My grandmother can only remember seeing her Bunch grandfather one time, which also indicates that he had moved from Ballard County. She and her brother George were in the 1870 census in her grandfather Scatt's home. George died at 16 years.
Information is scarce on the others.
Mary E. evidently married a Ready, with a son Joseph Ready, born 1859. There is a marriage record for Nancy and N.C. McLeon in 1857, however Nancy was in Joseph's household in 1860, still Nancy Bunch. Martha married a Dr. Coleman and they were living in Calloway County in 1880. Mary, Joseph's wife was living with them. My thinking is that Joseph moved to Graves or Calloway County where we lost him in 1863.
