Thanks for the additional info. My line is through Simon and Mary (Blake)'s son John Taylor b.1788 , who married Deborah Page, daughter of Coffin (not Noah) Page . He probably moved up to Gilmanton (the part which is now Belmont) with his father in 1800, as he was there when he married on 18 Dec 1807 (intents filed on 10 Dec. in N.Hampton) and listed in 1810 census for Gilmanton; in 1818 was "of North Hampton but now resident of Isles of Shoals" when selling his land up north . Later censuses keep him in N. Hampton (with him,at least in 1825, living in house on property of mother-in-law Betty Page,which was part of her dower and not land he and (now deceased) wife Deborah had sold her 16 years back), where it is probably him that died there on 9 June 1851 according to N.Hampton church records. The Book of Dow seems to be complete as to the list of his children, except for the entry of Betty Locke Dow, born 26 Oct. 1818 Belmont.I'm sure this is Elizabeth L. born 25 Oct 1808,their first child.
My line extends through son John T., born 1812 (said to be in Hampton, but also seen as Belmont (on IGI rec. but errs in both his middle name and name of father).
