As a girl, Bathsheba might have been enslaved by Ebenezer Pomeroy of Northampton, Massachusetts. She married the formerly enslaved Amos Hull, also of Northampton. The Hulls had five children, all born free- Amos, Jr., born in 1754; Asaph, born in 1755; Margaret, born in 1757 and died by 1761; Agrippa, born in 1759; and a second Margaret, born in 1761. Amos, Sr. died in 1761.
As a widow, Bathsheba owned land, prone to flooding and erosion, on an island in the Connecticut River. In 1767, the town gave her an ultimatum- sell to them, or see her house destroyed. She opted to sell and moved back to Northampton proper. Her second husband, Philemon Lee, had been "warned out" of Northampton and was in prison in nearby Springfield. In New England towns, people who couldn't support themselves were warned out- ordered to leave, so that the town would not have to support them. Fourteen-year-old Amos, Jr. went to nearby Hadley, 13-year-old Asaph was placed by the town's Overseers of the Poor in an apprenticeship in Connecticut, Agrippa, age nine, was sent to be fostered by friends of the Hulls in Stockbridge, Massachusetts, and Margaret, age 7, stayed in Northampton, but it is unknown whether she was allowed to live with her mother. Bathsheba and Margaret moved to Springfield in 1768, but were warned out and moved to Stockbridge without Lee. There, Agrippa cared for Bathsheba, who had become blind. She died there sometime after 1791.
