A Just and True Return: A Dataset of Pennsylvania's Surviving County Slave Registries

A Just and True Return (JATR) contains information about more than 6,300 Black people and their enslavers principally taken from extant registries from fifteen Pennsylvania counties: Adams, Allegheny, Bedford, Berks, Bucks, Centre, Chester, Cumberland, Dauphin, Delaware, Fayette, Lancaster, Northampton, Washington, and Westmoreland. It also includes a handful of records from four counties—Crawford, Franklin, Philadelphia, and York—whose registries have not been located, but which can be partially reconstructed from a variety of other sources.

Pennsylvania's 1780 gradual abolition law required enslavers to register with their county clerk any people they wished to continue holding in lifetime slavery. A 1788 law required that they do the same for any children they wished to hold in twenty-eight-year term slavery. Complete entries provide the name, age or birthday, race, and sex of enslaved people; the name, place of residence, and occupation of their enslavers; and the registration date.
