Robert Black 1
Robert Black, came to York (now Adams) county with the first settlers in 1740. He settled on a tract of land lying in Cumberland and Mountjoy townships. Rock Creek passed through the land. On this creek he erected grist and saw mills, and convenient to them a three-story stone dwelling house, the wonder of the neighborhood at that day but which would not be noticed now except for the immense thickness of its walls. Those dwellings were erected about the time of the Revolutionary War, and are all yet used for the purposes for which they were built more than one hundred years ago. Robert Black had two sons. James, the eldest, never married. Henry, the second son, married Mary, daughter of Thomas Weems, of Mountjoy township.
