Jonathan Kelley was born in 1840, in Michigan.
Jonathan was 21 years old and possibly living in Barry County, Michigan, when he enlisted in Company K on May 13, 1861. He was reported AWOL in August of 1862, but eventually rejoined the Regiment. Jonathan was listed as missing in action on May 3, 1863, at Chancellorsville, Virginia, but he soon returned to the Regiment. He was wounded in the leg on July 2, 1863, at Gettysburg, Pennsylvania, and was subsequently hospitalized, probably in Philadelphia, from July of 1863 until he was transferred to the Veterans’ Reserve Corps on January 15, 1864, at Washington, DC.
Jonathan probably returned to Michigan after his discharge and probably settled back in Barry County.
He was probably married to Charlotte Wright (b. 1841), and they had at least two children: Marilla (b. 1871) and Gertrude (b. 1865).
By 1880 he was working as a carpenter and living with his wife and two daughters in Barry, Barry County.
In 1878 he applied for and received a pension (no. 158884).
Jonathan died sometime between 1880 and 1890, when his wife Charlotte was reported living as a widow in Hope, Barry County in 1890. He is reportedly buried in Banfield cemetery, Johnston Township, Barry County.
