The picture shows you Washington County, Pennsylvania.  In the black square is a part of Fallowfield Township.  This is where both Thomas and Mary Carson and Hercules and Sarah Young lived in the last half of the 1700's.  Both are 6th Great Grandparents on my mother's side.  Thomas was born in Ireland and Hercules in Scotland.  It wasn't until two generations later that their grandchildren, Evan Young and Elizabeth Carson, while still living in Fallowfield married.  Both Evan and Elizabeth died in Hamilton County, Indiana.   ¶ 11:37 AM
