Hi Bob, John Davison came from Cumberland Co., PA and settled in Mecklenburg Co., NC by 1765. In that year he purchased land and was called "of Cumberland Co., PA". Later, the land he purchased was located in York District and later York Co., SC where he died in 1816. I am a descendant of two of his grandchildren, children of his son, Jacob. Would love to know how to fit in the family. After removing to Alabama and Mississippi, the family used the "Davidson" spelling.
