Leonards of Warwick, MA (1760-1820)

I am interested in the children of Moses and Harriet Beulah (Rice?) Leonard who settled in Warwick, MA. I am particularly interested in the family of their daughter Beulah Leonard (1735-aft 1790) who married Amos Marsh (1733-abt 1825)-- a marriage that ended in controversy when Amos ran off with the wife of a close friend.
