John Knowles m. (2) bef. 1 Sep 1752 Hannah (Wells) Calder, widow of John Calder of Wethersfield, CT.
[But note: on p. 79:387, in the list of children, a stillborn child b. 28 Mar 1751, and son John, bp. 12 Apr 1752, are both attributed to the second wife. Since first wife d. 1739, it appears the marriage probably occurred quite a bit earlier than the date given.]
