Searching for a wartime photograph of John Edgar Gurley, who served in the Thirty-third Wisconsin Infantry and 135th U.S. Colored Infantry. It may be possible that this photograph pictures him seated with his brother-in-law, 1st Lt. Horace S. Bradley: http://www.flickr.com/photos/8026096@N04/3178920465/in/set-72157606956971535/

Any and all help appreciated.
