He had been living in Hampshire County Virginia when he entered service in the Revolutionary War. He was drafted into service in the fall of 1780. He served two tours, totaling about 5 months, in 1780 and 1781.
In 1820, he was living not far from his son, Peter, in Ross County, Ohio.
He moved to DeGraff , Logan County, Ohio a "few years" before 1833. In that year, while a resident of Logan County, he applied for a pension for his military service in the Revolutionary War. He was rejected, due to having served less the the six-month minimum required to qualify under the Pension Act of 1832.
