Martha Workman was a witness to Elizabeth Lusk's 1770 will. Some have identified Martha as a Lusk (possibly based on her being a witness?). My Steel family came down from Lancaster County, Pa., to York Co., SC, about 1772.
In Martic Township, Lancaster Co., Pennsylvania, the Steels had neighbors named Lusk, McClelland, Workman, Wharry, and others similar to their neighbors on Fishing Creek in the Carolinas.
Did your McClellands and Lusks come down to S.C. from Lancaster Co., Pa.?
