HANNUM, HANUM Elizabeth, d. William, b. Apr. 24, 1645. [1 18] [Note: another entry says "Elizabeth, d. Will[ia]m, m. Apr. 24, 1645" from page 1:21, but this is probably a misrecording, or a misreading, of a duplicate recording of the same event.]
Source:Anderson, Robert Charles. Great Migration: Immigrants to New England, 1634-1635, Vol. III, p. 211, gives a fairly complete transcript of the father's will, and it does not (as Savage seems to suggest) identify Elizabeth's husband. Anderson points out that he only names her as Elizabeth, while the other two daughters are called by their married names, and Elizabeth gets over twice as much, all of which suggests she was not married at the time of the will (15 May 1677).
But there is time for the marriage to have occurred between the date of the will and Peter's first child (a son named John) born in 1680. In other words, Anderson's caveat may be entirely based on William Hannum's assertion of 1676 as the marriage date. There is circumstantial evidence that this marriage itself might have occurred: Peter's wife was named Elizabeth (the death of both Peter and his wife Elizabeth is recorded in Northampton in 1690). The first son was John, then a daughter Elizabeth, and since the first son John had died, a second son was named John, showing a commitment to that name.
