Samuel Gist was a wealthy British merchant who, toward the end of his life, lived in England, but owned a considerable amount of land with a large number of slaves in America. Upon his death in 1815, his will specified that within one year his slaves should be emancipated, and his estate was to provide them with a new beginning in the form of houses, churches, and schools. Because freed slaves were not allowed to live in Virginia, the Gist estate purchased land in Ohio. One of the tracts purchased in the 1830s was located in Highland County, Ohio, and it is the last surviving tract of land today.
