Searching for letters, journals, and other personal and public documents referencing the life and military service of Horace Seymore Bradley, who served in the Fifteenth Illinois Infantry. Pennsylvania-born Bradley (1833-1892) left the regiment in early 1865 to become first lieutenant and adjutant of the 135th U.S. Colored Infantry. His brother-in-law, John Edgar Gurley, served as colonel of the 135th. View a wartime photograph of Bradley: http://www.flickr.com/photos/8026096@N04/3178920465/in/set-72157606956971535/

Any and all help appreciated.
