Named as heir to estate of John Butterfield of Cambridge on 12 Jul 1791: "the heirs of Sarah Dickson deceased who was a daughter of said Testate's brother William before named, viz. Mehitable, John & David". [Note: No birth record for these children found: Source:Cutter, Benjamin. History of the Town of Arlington, Massachusetts, p. 233, suggests there might have been a daughter Sally and Elizabeth based on death records in Arlington, but he appears to be wrong.]
