Phillis might have been enslaved by the Rev. Chester Williams of Hadley, Massachusetts. When he died in 1753, his will granted freedom to a woman by that name. In October of 1765, Phillis Smith married Ralph Way, Jr. Both were from Hadley, Massachusetts. They had two children- Phillip, born in 1766 and died in 1768, and Nancy, born in 1768. Phillis might have died birthing Nancy, or soon after, as Ralph remarried in 1769.
