You provided the infomration in your Friday, May 26, 2000 posting that I have been searching for a long time. Do you have any of the backup documentation or sources? My undertstanding is that John Balzter Tarr had sons Christian, Henery, Peter, Frederick,Daniel and John. They went to Western Pennsylvania around 1795. Christian became a Congressman. My part of the family, John, went to Westmoreland County, PA, outside of Pittsburgh, and lived in a place called Tarrs or Tarrs Station, PA. Any further information you can provide would be great, including any source materials.
