Hagar was enslaved by the Reverend William Pratt of Easton, Massachusetts, who might have purchased her in Charleston, South Carolina, along with Heber, who was either her brother or husband. Pratt died in 1714, and his inventory lists Hagar and Heber as “two young negroes” valued at £52. In 1722, Pratt's widow freed the pair and provided them with 10 acres of land. On some records Heber's surname appears as “Pratt,” but he probably changed it to “Honestman” (also seen as “Honesty”) sometime after he became free. On June 26, 1733, or 1735, Heber married Susanna Cordner of Bridgewater, Massachusetts. If Hagar was Heber's first wife, she might have died before 1733.
