POTTER, Fones, of Coventry, son of Ezekiel, and Martha Hopkins, of Samuel; m. by Elder Elisha Greene, Oct. 21, 1782.
The 4 Oct might have been marriage banns since it doesn't explicitly say it was a marriage. However, the year was probably the same for both (probably 1781 based on birth of son Knight in about 1782).
