The information I have (which may not help much) is that Thomas W. Hollifield was the US Marshall. He had 2 wives, Luncinda Combs and Martha Hunt. The children are James ,Barbara,Cassandra,Elizabeth,Susan,Georgia,Andrew, Martha,William Robert,Rebecca,George ,Luncinda,Bartlet, Theonia and Samuel. They lived in Knott county Ky. Anyone of the children could lead to your grandmother... Good luck.
