The earliest group of items in the collection is a large series of childhood letters written by Sally Mundy to Edward Appleton, who appears to be a family friend or relative.

A significant part of the collection relates to a relief work mission to Jerusalem that Sally and Richard Ames embarked on in 1919 through September 1920. Sally and Richard Ames were members of a delegation of the Anglo-American Society, a Christian Science relief organization. The mother and son stayed in overseas on their relief mission through September of 1920. Sally Ames worked to develop the Jerusalem Laundry and Nursery, a business employing Palestinian women and providing childcare for their children.

During this period, Sally Ames wrote frequently to her family and friends and Richard and Sally Ames also corresponded with each other when Richard was traveling throughout the Middle East. These letters are part of a larger group of memorabilia relating to the family's stay in Jerusalem, which also includes photographs, journal and scrapbook fragments and other items of realia – such as the menus on the ship on which they sailed to Egypt.

Shortly before Sally and Richard Ames left New York City for Jerusalem, they became acquainted with another member of the Anglo-American Society, author Talbot Mundy. Mundy corresponded with both Richard and Sally in 1919 and early 1920, before joining them in Jerusalem in February of 1920. Once in Jerusalem, Mundy developed a romance with Sally Ames and their letters to each other through the early 1920's are a highlight of the collection. During his stay in Jerusalem, Mundy helped to develop the first English language newspaper published in Jerusalem, the Jerusalem News. The paper was edited by historian and Anglo-American Society member, William Dennison (W.D.) McCrackan. Talbot Mundy was a chief correspondent and substituted as editor when McCrackan was traveling. The collection includes complete issues of the papers edited by Mundy, as well as clippings of articles by and relating to Mundy, Sally Ames and the work of the Anglo-American Society. Additional material relating to Mundy includes some of his business correspondence, financial records for the failed investments in Liafail, Mexico that he became involved with in the late 1920's, and a humorous poem written to his publishing company, Bobbs-Merrill.

Sally Ames married Talbot Mundy in 1924 and the two remained married until 1931, although they separated in 1928. During the early period of their marriage, the couple moved to Southern California and became involved in the Point Loma Theosophical Society, led by Katherine Tingley. The collection includes clippings and photographs of their home and activities in Point Loma and literature relating to the Theosophical movement. After Sally and Talbot Mundy became estranged, Sally remained in California with her son Richard and his wife Elizabeth Jean (Betty) Ames. The remainder of the collection includes a great deal of tax, real estate, and financial documents of both Sally Mundy and Richard Ames, as well Richard Ames's business correspondence and his correspondence with Iverson L. Harris and Peter Berresford Ellis in regard to biography of Talbot Mundy.
