Samuel Sewell's diary says this: "July 31, 1704...call at Capt. Mors's [in the evening in Medford] and he tells us of the Indians assaulting Lancaster."Collections of the Massachusetts Historical Society, vol. 6 (Boston: 1878), 114. It's plausible the news of the attack was brought to Medford the same day.In the published Lancaster vital records, Henry Nourse, the compiler and editor, inserted a section called "Killed in Assault by French and Indians, July 31, 1704."[5] The list includes "Lieutenant Nathaniel Wilder, aged fifty-four years." No source is provided and is therefore unreliable as to his age, especially given Nathaniel's 1655 birth record. This may be the source for many other references to his death that change his birth date to 3 November 1650.
