Many genealogies have Samuel's date of death as 18 March 1763, a date of death shown in the Barbour Collection for a Samuel Remington. However, that date cannot pertain to this particular Samuel, for reasons stated below.
Samuel Remington is named as Executor in the will of his sister, Hannah Leavitt, dated 3 Feb 1769. The documents show that Samuel presented the inventory of her estate on 15 June 1769 at Suffield.
Two entries in the Barbour Collection of vital records refer to him as Samuel 2nd, but the death date of 1763 does not say Samuel 2nd. Furthermore, it has no age at death.
Findgrave.com shows the headstone of Samuel Remington who died 17 Aug 1788 in 82nd year of his age; this agrees with his birth year of 1707 (he would have been age 81 when he died in his 82nd year).
