His death is recorded as on March 5, 1770 in the town records, but, as on the 9th in the Church Records, aged 72; Elizabeth Bellingham mentions him in her will of [November] 1697. I have not found the place of his burial. [The Boston Evening Post for Monday, March 12, 1770, has the following notice: "Last Monday Evening died at his Seat in Chelsea, and on Friday following was decently interred in this Town, the Honorable Samuel Watts Esq; formerly one of his Majesty's Council for this Province and for many Years past one of the Judges of the Court of Common Pleas for this County."]
