Isaac Hall was born in 1802 or 1805 in Latintown, Ulster County, New York or in Vermont.
Vermont native Isaac was married to New York- or Ohio-born Betsey (b. 1821) and they had at least five children: John (b. 1843), Abigail (b. 1845), George (b. 1847), William (b. 1854) and Alanson (b. 1855).
By 1843 Isaac and his wife had settled in Michigan, and by 1850 they were living on a farm in Paris, Kent County. Isaac was still farming and living with his family in Paris in 1860.
Isaac was a 60- or 57-year-old farmer probably living in Paris, Kent County when he enlisted in Company G on February 13, 1862, at Grand Rapids for 3 years, and was mustered the same day. He was discharged for disability on June 15, 1862.
It is not known if Isaac returned to Michigan after his discharge from the army.
No pension seems to be available.
