He was a farmer in his native town, serving also in various town offices, and especially as Clerk of the Probate Court, of which his father was for some years Judge.
He died in Mansfield in June, 1794, in his 55th year. His estate was bequeathed to his widow, and to his brother and nephews and nieces.
He married Anna, third daughter of Peter and Rebecca (Storrs) Aspenwall, of Woodstock and Windham, Connecticut, who was born on October 26, 1748, and died in the early part of the year 1807.
