Series III, “Photographs, undated,” contains four albums containing multiple photographs. The subjects of these photographs are primarily members of the Mitchell family, their friends, and events of import, and were the property of Silas Weir Mitchell and Marion Lea Mitchell. Though some photographs have been annotated, the collections compiler has also provided item-level description of each photograph. These descriptions can be found under each individual album in the container list below. The albums are arranged numerically according to the numbers assigned to them by the compiler.
