Joshua Burrell lived in Edmeston, New York, when he married Caroline Fitts. Edmoston is just south of Leonardsville, a hamlet in the town of Brookfield. "As with many small communities, Leonardsville was given its name by the Post Office Department, which in this case named if after Reuben Leonard who, in his early years, ran a local grocery and dry goods business that became a convenient location to drop off mail for local residents." (Wikipedia) Could Reuben have been related to Russel Leonard, the husband of Sophronia Burrill?
