Garnett Day and Nancy Sayles Day papers consist of business records, correspondence,
genealogies, photographs and other material from the Day and Sayles families. Much of
the material concerns the Collins-Day South American Expedition of 1914-1915, Lee
Garnett Day’s military career, the Bennett-Day Importing Company, and both Lee Garnett
Day's and Nancy Sayles Day's travels around the world. The collection is dated from 1890
to 1968. Most of the material is dated from 1911 to 1945.
The Elmer Ephraim Ellsworth Papers, covering the period 1854-1861, consist of correspondence, a journal fragment, drafts of his writings, and sketches concerning Ellsworth's involvement with the Illinois Militia, the United States Zouave Cadets, and the New York Fire Zouaves, along with memorabilia about Ellsworth and his military career that was produced some time after his death.
The Henry Knox Thatcher papers consist of an oil painting of the U.S.S. Constellation, military memorabilia, and three journals and logs kept by Thatcher while on board several ships, including the U.S.S. Brandywine (1839-1841) and the U.S.S. Constellation (1862-1863). The journals reflect ship life, diversions on shore, the social and political climate of his time, and the duties of American ships in the Mediterranean during the early years of the Civil War.
