Daniel Witcher left Virginia after 1800 and died in Smith County, Tenn. in 1815. His wife was Susannah DALTON, not Key,daughter of Robert Dalton, Sr. and Mary Key.Mary was a daughter of John Key and Martha Tandy of Albemarle County, Va which explains the Tandy and Key middle names for the Smith County Witchers.
Goad, Young, Wakefield, Witcher, Ramsey and other Pittsylvasnia County families (Sutton, Parsons ?) all arrived in Smith ca 1804 so it may have been a wagon train.
Another Daniel left a will in 1808 Pittsylvania (I have an extract) and the 1810 tax list for Cabell County, Va showsx two Daniels, Sr. and Jr., neither the above two.
