The Mary Margaret Frank Papers include a number of items relating to the genealogy of the French family. Two different books, Ancestors and Descendants of Samuel French the Joiner, and The Family of David Scott French, examine the history of the French family from the 1600s through the 1900s. The Mallory and French papers establish a connection between the two families four generations before Mary Margaret French Frank was born in 1912. This folder is followed by one which contains material related to French Frank’s immediate family.

Those folders that do not deal specifically with the genealogy of the French family include a folder on Samuel S. Townsley, who was French Frank's maternal grandfather. Mary Margaret French Frank contributed one of her mother’s letters which was used in the publication Humanities on the Frontier. Blanche Harding was a friend of both Mary Margaret French Frank and her mother, Mabel.  John French Jr.’s connection to the other French family could not be established, while the folder on Skulda Banér, an author who wrote about a woman who left home to become a teacher in North Dakota, has no relation to the French Family. Also included is one folder of Frank's correspondence, one scrapbook, and biographical information regarding Buron Townsley French.

One oversize folder was placed in the Oversize File Cabinet. The folder contains an original deed for land owned by a “John Whitney” in the Province of Upper Canada, 1804. Whitney’s relation to the French family is unknown.
