Mary Richardson, d/o William Richardson and Elizabeth Colburn, b. 18 apr 1728, m. Capt. Reuben Butterfield of Tyngsborough.
Source:Gordon, George A. Butterfields of Middlesex says Reuben had a son Levi, b. 1751 who d. in infancy, then says Joseph was born 20 May 1756, and that it was Sarah, not Joseph, that was born 8 Jan 1759. This may be true, since it fills some significant gaps in sibling births. But according to the published VRs for Tyngsborough, there is neither birth nor death record for the first Levi, and the birth record for Joseph says 8 Jan 1759, and there is not a birth of Sarah on record.
