The record that I have shows that Joseph Flautt's wife was named Mary. They had five sons. One of them, Jacob, had a daughter, Elizabeth who married George Sleasman in 1823. George and Elizabeth had a daughter, Cathrine Lauretta, in 1826.
George Sleasman was the son of a George and Margaret Sleasman. This George was the son of Paul and Eva Sleasman. Paul Sleasman died in 1778.
Pennsylvania Archives lists a Capitan George Sleasman in the 5th Battalion, York County Militia, 1783.
