The Louis and Mary Ruth Jones Collection reflects the lives of several generations of Quaker families—Jones, Mather, Evans, Newlin, Brown, White, Parker, and others—in Pennsylvania, the Carolinas, and especially Ohio, Indiana, Iowa, and Kansas between 1800 and 2000. Of special interest are extensive materials on the establishment of Quakerism in Cuba through the work of Louis Jones’s parents, Sylvester and Mae (Mather) Jones.
