"Page 4. 8. IV. William m. secondly Hannah, daughter of Daniel Henchman."
↑ Marriage estimate of before 1679 is based on birth of son William in Boston 22 Nov 1679 (see Boston Births, p. 149). Hannah witnessed an indenture dated 7 Aug 1678 as "Hannah Henchman" (see Suffolk Deeds, Vol. XI, folio 47, p. 149) so the marriage occurred after this date; and probably by Feb 1678/79 based on the birth of their son.
The Hinchman Heritage Society web site gives a date of 15 August 1678 for this marriage, but does not provide a source for that date.
