The collection contains minutes, constitutions, treasurer’s book and correspondence about upcoming reunions concerning the Old Third Michigan Association, 1870-1927, n.d. Also in the collection is a regiment roster, and photographs of men who served in the Third Michigan Infantry during the Civil War. Of special interest are the “Civil War Letters” by Charles H. Church, published in 1987 and a “History of the Old Third Michigan Infantry” written by Steve Soper, 1996. A photocopy of an unidentified newspaper article from 1861 lists the officers of the unit.
