Children of Abraham Belknap and Mary ---: 3) "Samuel, said to have been b. 1627/8 (but proof of this statement seems lacking); living 1731; m. bef. 1653 Sarah Jones, dau. of Robert and Elizabeth of Hingham." "...in 1696 he conveyed land there [at Haverhill] to his sons Ebenezer and Abraham, one of the deeds being acknowledged by him as late as 31 Aug 1731." [Note: proof of birth may be lacking, but marriage in 1653 suggests by 1632 which is not much different. Living in 1731 seems doubtful, as that would make him 100 by conservative estimates. Text of the deed would be helpful to see if there is possibility of confusion with his son.]
Abraham Belknap had a number of children baptized in North Weald, co. Essex ... Immanuel, bapt 16 March 1627/8, "evidently a clerical error for Samuel". Regarding Samuel living in 1731: "This is an error, for the Samuel living in 1731 was evidently Samuel's son, Samuel, born 1 May 1662." [No evidence, but pushing the birth back into the 1620's makes it even less likely it was the father.]
