Known to be living 26 Aug 1718, but administration of his estate awarded to his son on 7 Apr 1719.
↑ I have found sources that say he was alive in 1729, but given that he had a son named Elihu Gunnison, I believe them to be mis-identification, given the information about his estate listed in the sources. (For example: Source:Old Kittery and her families (326632), p. 479.) Source:Vital records of Kittery, Maine : to the year 1892, p. 67, on 18 Aug 1729, lists the third Elihu Gunnison (grandson) as "Jr.", indicating the grandfather was actually no longer living in 1729.
