After receiving your reply I looked at the Turners on the 1850 Cobb County census. Nancy is approximately the right age but the record indicates that she was born in Georgia. The children of Thomas Culwell were all born in North Carolina. Thomas Culwell or Caldwell was my gr-gr-gr-gr grandfather. He had nine children, including one named Nancy. The family migrated to Arkansas, then to Texas. This is probably not your Nancy. Perhaps, however, she is related to Thomas through a brother. I have no information about siblings for Thomas. Keep in touch.
