The Buchanan family fonds consists mostly of correspondence, invitations, photographs, books and other types of documents. The records pertain to the years that George and Lilla Buchanan were residents of Sudbury. Most of the correspondence is between Lilla Buchanan and her family and friends. There are also letters of congratulations for the appointment of George Buchanan as King's Counsel. A program, photographs and a newspaper clipping document the Royal Visit to Sudbury on June 5, 1939. The photographs of the fonds depict the Buchanan family and their friends. There are also 11 copies of photographs depicting Sudbury in the early 1900s, people of the community, and early railway construction.
