TAFT, Joseph and Elizabeth Thayer, int. Jan. 23, 1740-1.
↑ There may have been an earlier son Thomas who died 5 Jun 1751, since such a death record is found. If so, he obviously did not live to adulthood. A misrecording can't be ruled out, so no such birth was assumed. See the discussion here. This website doesn't include Margaret/Peggy, but her baptism clearly indicates her father as Joseph Sr., which would put her in this family.
