The General Duncan Lamont Clinch Collection contains mostly correspondence and newspaper clippings about General Clinch. Topics range from family matters to his military campaign in the Second Seminole War and include letters from the Secretary of War at the time, Lewis W. Cass. The newspaper clippings pertain to General Clinch's defense of his actions during the Second Seminole War and at the Battle of the Withlacoochee. Also included in this collection are a number of land transaction documents and bills of sale. There are also newspaper clippings and letters about Clinch's first daughter, Eliza Bayard Clinch, who was married to the hero of Fort Sumter, General Robert Anderson. There are also copies of several wills from General Clinch's children, several letters of correspondence from within the family, and Clinch's autobiography written in the form of a letter to his sons. Portions of this latter document are missing.
