[See following comment: the quoted portion taken from this source is completely erroneous.]
Children of Amos Hyde and Susanna Foster: Amos, b. 1 Oct 1769, "m. at Newton, 16 July 1805, his third cousin, Lydia Hyde (30, ii), b. at Newton 6 Feb. 1780 , dau. of Daniel and Rebecca (Frost)."
[Note: It is not clear why this source didn't recognize the seemingly very precise death date, cited above, as belonging to this Amos, and gave it instead to the father. The will of the father shows he died in 1808, and his will makes no mention of a son Amos, showing his son predeceased him. Further, the real estate of Daniel Hyde (Middlesex Probate 11225) is settled on his eldest and only son Abraham on 12 Mar 1806, who is to pay his sisters "Hannah, Asenath, Patty & Prudence". No daughter Lydia is mentioned. Which is not surprising, since Newton VRs (p. 466) show the death of Lydia, d. Daniel, on 1 Jan 1804. There is a marriage in the Newton VRs, p. 315, of an Amos Hyde to a Lydia Hyde on 16 Jul 1805, but it appears this source has identified neither participant correctly.]
