Martin is said in some sources to be the grandson of Revolutionary War soldier Moses Ainsworth; this needs further verification.
On 4 October 1861, Martin enlisted as a Private in Company I, of the 74th New York Infantry. On 27 July 1864, he transferred to Company G of the 40th New York Infantry, and was discharged on 17 May 1865 due to disability and a gunshot wound. He received pension certificate number 96.038.
On 04 Mar 1868 Martin married Annette E Dyer in Calais, Vermont. She was a widow and the daughter of Thomas McKnight.
He was admitted to the National Home for Disabled Volunteer Soldiers, at Togus, Maine, 3 October 1911, suffering from a carcenoma of the neck and pulmonary tuberculosis.
Martin was described as 5'8", with a light complexion, blue eyes and black hair. He was Protestant, a married man, and a mill man by trade.
After the war he lived at Craftsburg, New Hampshire. Martin gave his next-of-kin as Gaines M. Ainsworth, his son, in Richmond, Vermont.
