This series contains photographs and other papers which represent the lives of the Wilder family and their extended relatives. The Wilders have familial connections to the Tappan, Porter, Lewis, and Niven families. Some of these connections are apparent through photographs or the extended genealogical research that family members did into their own lines. Some of the photographs could be identified while others could not be. Also included in this series are the papers of various family members including Amos Tappan Wilder's collection of materials related to his uncle's works, Thornton MacNess Niven's sermons, and materials related to Thornton Wilder's memorial service.
