Bates (1) lists two George Alcorn's: one in company D, who was mustered in on 3 October, and not accounted for when the regiment mustered out, and one in company F, who was mustered in on 2 October, and was discharged on surgeon's certificate. The company D register of men transferred indicates that they are the same person. Unfortunately, the Pennsylvania Archives cards have inconsistent information about them. Because he was first in company D, I have preferred the information on the company D card.
He was 28 years old when he was enlisted (3 [18], 4 [28], 7 [28]). He was born in Harrisburg, Pennsylvania (7).
He was a soldier when he was enlisted (7).
He was 5 feet 5-3/4 inches tall, and had a dark complexion, dark eyes, and dark hair (4 [light complexion], 7 [dark complexion]).
He was enlisted and mustered into service on 2 or 3 October 1861 (1 [co.F 2 Oct, co.D 3 Oct], 3 [3 Oct], 4 [2 Oct], 7 [2 Oct]). He was enlisted for three years, by Lieutenant Pierce, at Philadelphia, Pennsylvania (3, 4, 7). He was mustered in as a private, at Philadelphia, Pennsylvania (3, 4). He initially served as a private in company D (1).
He was transferred to company F on 31 October 1861 (2).
He deserted from Alexandria, Virginia, on 11 June 1862 (5, 7).
He was discharged, at Washington DC, on surgeon's certificate of disability (1), on 21 August 1863 (1, 4, 6, 7).
