He was 41 years old when he enlisted (2). He was born in Tirone County Ireland (2). He was a laborer (2).
He was 5 feet 9 inches tall, had a dark complexion, grey eyes, and dark hair (2).
He enlisted and was mustered into service for three years in company E on 9 September 1861, at Philadelphia Pennsylvania (2). (Bates (1) has 9 September 1863, which is obviously a mistake, given the date Bates has him deserting.) He was enlisted by Captain Lentz, and mustered into service by Colonel Reiff (2).
He deserted on 8 October 1861, at Philadelphia Pennsylvania (1, 2, 3).
