Marshall Hammond was born in 1844 in La Porte, La Porte County, Indiana.
Marshall left Indiana and moved north to Michigan sometime before 1860 when he was working as a day laborer and mechanic working with John Holland, a railroad worker, in Ovid, Clinton County, and probably living at the Railroad Hotel in Ovid.
Marshall stood 5’7” with blue eyes, light hair and a light complexion, and was 17 years old and possibly living in Ingham County when he enlisted in Company D on May 13, 1861. (He was possibly related to Benjamin Hammond and George Hammond, both of whom would also enlist in Company D.)
Marshall was discharged on July 29, 1861, at Arlington Heights, Virginia, due to “general debility subsequent to rubeola (measles).”
No pension seems to be available.
