Peter, Jr. was the son of Peter, Sr. and Azubah Newport of Hatfield, Massachusetts. He was born into slavery about 1765-1770. Peter lost his mother in 1775, giving birth to a sister who died as well. In 1779, while still enslaved, his father bought a farm in nearby Williamsburg and remarried. The family's enslaver, Joseph Billings, stipulated in his 1781 will that "the children of the said Peter, to wit Jonah, Peter, Eliphalet and Amos, shall be manumitted and set free as soon as they shall arrive, respectively, at the age of twenty-one years; in the mean time they shall be subjected to, under the control of, and in the immediate service of, my aforesaid loving cousins David Billing and Silas Billing." Joseph Billings died in 1783, when Peter, Jr. would have been less than 21 years old. He died in his 40s, unmarried, in Williamsburg, Massachusetts.
