Raymond V. Shepherd, Jr. studied the Stenton estate for his 1968 dissertation,
James Logan's Stenton: Grand Simplicity in Quaker Philadelphia, for an M.A. in American Culture from the Winterthur Museum Program at the University of Delaware. The Ray Shepherd files on Stenton, 1968-2003, primarily consist of Shepherd's research materials and correspondence regarding Stenton and James Logan, although there are also some letters and documents that pertain to other 18th century historic sites. The bulk of materials are secondary-source, including historic site reports, articles, newspaper clippings, citations, and a large quantity of photographs of furniture and decorative objects.
