Scipio was enslaved by Joseph Hill, and then by Capt James Littlefield.
"Scipio, a Negro" was baptized as an adult on December 6, 1741 "in the Church of Christ in Wells, upon ... having made a personal, express, publick Profession of Christianity."
"Scipio, a Negro" was "received to full Communion by the Church of Christ in Wells" on October 30, 1743. It is presumed that these baptism and communion records refer to the same person.
"In addition to those stated in his will, Joseph Hill owned Dinah and Scipio." - Bourne, p. 408
On Oct 19, 1741, Joseph and Sarah Hill brought "Tom, a Negro" and "Will, a Negro" to be baptized as infants "in the Church at Wells." Since Jos. Hill brought Tom and Will to be baptized in 1741, the assumption has been made that the Scipio who was baptized in 1741 is the same individual as the Scipio that Bourne states was owned by Jos Hill.
Whereas Capt James Littlefield is said to have enslaved four individuals (Scipio, Sharper, Dinah and Tom) with the same names as six of the people enslaved earlier by Joseph Hill, the presumption has been made that these were the same individuals.
In her listing of "African Americans mentioned by Bourne and Remich" at the BSM exhibit on the Ridge Community, Town Historian Kathy Ostrander Roberts also lists those individuals as having been enslaved by both Joseph Hill and Capt James Littlefield.
