Henry's will at Warwick was dated 30 Dec 1764, proved 28 Jan 1765 or 2 Feb 1765. He mentions sons Henry, Charles, and Waterman, and daughter Phebe. In November 1764, both Charles and Elizabeth Tibbetts died. It is not clear whether these were Henry's children or grandchildren. Henry himself died not long after they did. Capt. Samuel Tillinghast of Warwick recorded these deaths in his diary. The entry for 17 Jan 1765 reads, "Last night died Henry Tibbits, Who has been Long Ill with Many disorders. This is the third out of this Famely in about two months." Editor Cherry Fletcher Bamberg tells us that "John Gorton preached at the funerals of Charles and Elizabeth Tibbits on 16 Nov. 1764 and then at Henry Tibbits' funeral on 18 Jan. 1765." According to "John Gorton's Papers," Elder Gorton's text at Henry's funeral was Isaiah 55:3.
Cherry Fletcher Bamberg's book entitled "Elder John Gorton and the Six-Principle Baptist Church of East Greenwich, Rhode Island" says that Henry was the second son of his father Henry. It reports that he joined the Six-Principle Church of East Greenwich on 19 August 1754, and records that he contributed to repair the meetinghouse in 1763.
Henry was under 21 in 1708 when he was mentioned in his grandfather's will (NK 5:139 - 142). Some records say that he died 17 Jan 1765, but Capt. Samuel Tillinghast's Diary says the 16th.
