The Bragdon Family Papers are predominantly composed of the personal papers of architect, author, and theater designer Claude Fayette Bragdon but also include those of his parents, sister, wives and children. Included is the correspondence of Claude F. Bragdon with his family and others, including Gelett Burgess, Walter Hampden, Norman Kent, Jiddu Krishnamurti, Kathleen Cunningham, Llewelyn Powys, J.B. Priestley, Nikolai Roerich, Alfred Stieglitz, Peter Uspenskii, John Van Druten, Tennessee Williams, and Frank Lloyd Wright. There are also publications and manuscripts by Bragdon; financial and legal papers; photos of buildings he designed; drawings of stage sets; scores for color music; diaries, 1877-79, 1908-12, 1924-46; scrapbooks; records of the Manas Press; and memorabilia. The correspondence and manuscripts of his sons, Henry W. and Chandler, his father George C. Bragdon, and that of his wives, including the spirit communications of his second wife are included. In addition, the diaries of Kathleen Shipherd Bragdon, 1860-1920; letters and papers of Fayette Shipherd and family; scrapbooks and diaries of May Bragdon; family photographs; and genealogical data; and documents relating to building of Selkirk Bethel Church (Point Ontario, New York, 1848-55) are contained in the collection.

The collection consists of letters written to Arthur Barry by his sons H. Brewster Barry and H. Pomeroy Barry, other relatives, and friends. There is also correspondence with the officials of the schools the boys attended, as well as letters concerning the property Barry owned, and his financial and business affairs. The rest of the collection includes Barry's private journals, personal financial and tax records, and the reports and correspondence of the charities and clubs with which he was affiliated. The correspondence and records of the East Side Savings Bank, the Community Savings Bank, and the Rochester Trust and Safe Deposit Company make up the balance of the collection.

The correspondence, nearly all of which is to other writers, discusses the work both correspondents have in progress and their reactions to various plays. A letter to Ellis discusses Bax's Victorian upbringing; the Kilgour correspondence is centered around the Playwrights' Club; the Lafitte Cyon letters make frequent mention of Meum Stewart. The manuscript genealogical materials trace the Tingle and Lea branches of the Bax family; their compiler is unknown.

The first two boxes of the collection contain exhibits compiled by Francis Bellamy's son, David, in his effort to establish the authenticity of his father's claim. The following four boxes include correspondence about the pledge controversy, speeches and articles written by Francis Bellamy, along with news clippings and articles written both about Bellamy and the pledge. This collection is closely related to collection D.147, David Bellamy Papers, 1892-1980.
