Bates (1) lists two Henry Ache's: Henry M Ache, in company A, and Henry W Ache, in company I and the 118th PA. The pension index (2) makes clear these are the same person.
He was born on 30 October 1847, in Lower Saucon Township, Northampton County, Pennsylvania, to John O Ache and Sarah Wasser (4, 5). He was 17 years old when he enlisted in 1865 (3, 6, 13, 14 [62 in 1910]). He was born in Easton, Pennsylvania (3, 13, 14).
In 1860, he was living with his parents, in Lower Saucon Township, Northampton County, Pennsylvania (9). He was 13 years old, and had attended school in the previous year (9). His father was a segarmaker (9).
When he enlisted, he was a cigarmaker (3, 13 [sai[lor]?).
He was 5 feet 2-1/2 inches tall, and had a dark complexion, gray eyes, and brown hair (3, 13 [5'5", light complexion, grey eyes, light hair]).
He was a substitute (1, 3, 6). He enlisted and was mustered into service as a private on 23 March 1865 at Easton, Pennsylvania (1, 2, 3 [could be 28 March], 6, 11, 13, 16). He served in company E of the 118th Pennsylvania Infantry (1, 8, 16). (The only record of his service in the 118th Pennsylvania is in the 91st's company I rolls (6).) He was enlisted for one year, at Easton, Pennsylvania, by Captain Yohe [?] or Bottle [?] (3, 13). His enlistment was credited to the eleventh congressional district (3).
On 2 June 1865, he was transferred to the 91st PA, where he served as a private in companies A and I (1, 5 [mentions co.I only], 8, 12, 16).
He was absent, sick, when the regiment mustered out (1, 3, 6, 13 [discharged on muster-out rolls]). He was discharged on 14 July 1865 (11, 16 [10 Jul]).
In 1870, he may have been living in Lower Saucon Township, Northampton County, Pennsylvania (15). (The only census entry I've found that could be his is for Henry Acha, with foreign-born parents.) If so, he was a laborer (15).
He was married to Matilda W Mushlitz on 9 July 1870 (5). She was born on 26 April 1851, in Lower Saucon Township, Northampton County, Pennsylvania (5).
They had nine children (5):

In 1910, he was living in Hellertown Borough, Northampton County, Pennsylvania (14). He was living with his son Vincent and Vincent's family (14). He was a widower (14). He was a machinist, at a steel works (14).
