Series 3: Correspondence consists largely of letters addressed to LLES, 1908 to 1967. The letters are filed chronologically; they are not filed by correspondent.

Most of the letters are from friends of the Spelmans. In the letters are acknowledgments for gifts, appreciations for visits with the Spelmans, descriptions of travel plans, reports of health, and a mutual sharing of cultural interests. The letters reflect the generosity of the Spelmans toward a wide circle of friends in the United States and Europe. Business letters related to Leolyn's trust fund held in Cleveland are included in the folders for 1938. The Spelmans lived a lifestyle beyond the means provided for Leolyn in the trusts established by her parents, and their business letters are filled with advisements for a turn to moderation. The smaller amount of TMS correspondence in the collections is concerned with loans or the delay of payments.

Two sections of the correspondence are particularly interesting. Folders filed 1908-1919 (Box 27) contain a series of letters written to LLES from her mother, Josephine Everett (d. 1937). Mrs. Everett's letters, written almost entirely during the period when LLES was living in New York City, are filled with considerate parental concerns. Because LLES had always expressed animosity towards her mother, the letters suggest a different view of Josephine Everett.

A second group of letters from the years, 1938-1945, were sent from Spelman friends who remained in Europe either by choice or circumstances. Letters written from England, Italy, and Switzerland are poignant in their descriptions of the deprivations and wartime conditions in Europe.
