Sarah Hill left "a Negro servant John" to her grandson William Sayer in her 1768 will.

"Sarah Hill of Wells, widow, devises, 28 Oct 1768: after debts and funeral charges are paid, to my grandson William Sayer of Wells, my executor, my Negro servant John & all the remainder of my estate real & personal." - Frost, p. 637

From the Last Will & Testament of Sarah Hill of Wells dated 10/28/1768: "I give to my grandson William Sayer of Wells my Negro servant John." It is unclear whether this Sarah Hill was related to, or is possibly even the same individual, as the Sarah Hill, wife of Joseph Hill, who inherited Tom and Sharper from her husband in 1742 or 1743.
