Material compiled from Robertson, Michigan in the War, Michigan Volunteer Registry database on SeekingMichigan.org, and online databases of the Sons of Union Veterans of the Civil War and Find A Grave.

Belton was “dismissed the U.S. service to date April 20, 1863,” for cowardice. Annual Report of the Adjutant General for the State of Michigan for the Year 1863 (Lansing: John A. Kerr & Co., 1864), 130.
 Death date is from City of Port Huron website; if accurate, Gilby’s birth year was 1849 or 1850, making him not 15 at enlistment as fifer on Jun. 18, 1862, but 12 or 13.
