John Marsh was born in 1846 in Ionia County, Michigan.
In 1860 there was a 13-year-old John Marsh, born in Michigan, living with the William Scranton (?) family in Eureka, Montcalm County.
John stood 5’5” with blue eyes, light hair and a light complexion and was an 18-year-old farmer possibly living in Muskegon, Muskegon County when he enlisted in Unassigned on February 10, 1864, at Grand Rapids for 3 years, crediting Muskegon, and was mustered the same day.
There is no further record and there seems to be no pension record available.
(Interestingly, there was one John R. Marsh, age 18, who enlisted as a Private on February 10, 1864, in Company A, Fifth Michgian infantry, for three years, and was mustered the same day. He was mustered out at Jeffersonville, Indiana, on July 5, 1865. It is possible that he was the same John Marsh, age 19, who enlisted in or was reassigned to Company I, Twelfth Michigan infantry on January 27, 1864, at Weesau (?) for 3 years, and mustered on February 4. If so, he died of disease at Huntersville, Arkansas, on July 2, 1864, and may be buried in Little Rock National Cemetery: no. 1005. See U.S. Quartermaster General’s “Roll of Honor,” vol. 8 p. 23: John Marsh,” laborer, who died on August 15, 1864.)
In May of 1931 one John H. Marsh, then living in Michigan, applied for a pension (no. 1691770) based on “unknown” service in a Michigan infantry regiment.
