"Thomas, Andover, … m. 15 Dec 1664, Sarah Steward … had … Nathaniel, (b.) 9 Jan. 1678 [sic]; …"
"Nathaniel, perhaps of Ashford, s of the first Thomas of Andover, m. 1710 Mercy Hutchinson of Ashford, had Nathaniel, b. 1714; and no more is told of him."
[Note: Savage appears to have gotten the birthdate wrong, see here which says 19th January, not 9th. By Savage's usual conventions, 1678 means 1677/78, but by spacing of siblings and context of surrounding records and typical usage, this was 1678/79.]
