He was born in Paris, France (9). He was born in 1824/25 (9 (37 in 1862)).
See the census transcriptions below for some possible Louis Happy's (11, 12, 13). (Given the birthplaces and child's age, the 1880 Louis Happy is probably not this Louis Happy; the 1860 and 1870 Louis Happy's may be the Louis who served in the 91st. But note the birthplace and occupation.)
When he enlisted, he was a farm[er] (9).
When he enlisted, he was 5 feet 7 inches tall, and had a dark complexion, dark eyes, and dark hair (9).
He was enlisted on 23 July 1862, for three years, at Alexandria, Virginia, by Captain Henry (9). He was mustered in on 29 July 1862, as a private in company H, at Washington DC, by Captain Dodge (1, 9, 14). He was paid $29 in bounty and premium (9).
