I have here a Jane McCormick who was born 1751. She was the daughter of Samuel McCormick and Mary Blair.
Samuel died on Jul 1765 in Carlisle, Cumberland Co. Pa and was born in Ireland. Part of the English movement to migrate Protestant scotch to Catholic Ireland so the Protestants would be on the English side when the time came for Ireland's counties to vote for their freedom, hence north ireland.
Could this be Our Jane McCormick who married William McNees, possible son of James McCormick??
