'He m. ... (2) at Cambridge, Mass. 4 Jan. 1653 [citing AEBK, p. 205], Mary (____) Grissell, who d. at Charlestown 17 May 1685, widow of Francis Grissell of Charlestown.'
''WILLIAM ... married second Cambridge 4 January 1653 MARY (_____) (_____) GRISWOLD, died by 9 9mo 1655 (Middlesex Deed 1:152-53) ...'
The same 9 Nov 1655 deed is cited by Stott and Hyde as evidence that William's second wife Mary was the widow of Francis Grissell. However, they do not interpret it as meaning that Mary had died by then.
