I am descended from Henrietta Augustin, Charles' sister. I have some fairly extensive information regarding Henrietta's family (she married Frank Bullinger in the early 1860s); if you would like more details, please let me know.
Of particular interest to you is the following entry from the "Commemorative biographical record of the Fox River Valley counties of Brown, Outagamie and Winnebago" 1895:
CHARLES F. AUGUSTIN, proprietor of the Menasha Saturday Evening Press, is one of the wide-awake progressive business men of Menasha who have done so much to make the city what it is.
He is a native of Prussia, born July 11, 1839, in the village of Rodden, near Leipsic, a son of Godfrey and Frederica (Tostleben) Augustin, who were the parents of seven children, named, respectively, Henrietta, Charles F., Gustave, Christianna, Julius, Frank and Henry. In 1853, when Charles F. was a foureen-year-old boy, the family set sail for America, landing in New York in July, from which city they came west to Milwaukee, Wis., where they made their home two years. In May, 1855, they settled on a farm in Harrison township, Calumet county, where the father died in 1866, the mother afterward moving to Oshkosh, where she passed away in 1891.
Our subject received a liberal education at the public schools of his native land, and after coming to this country assisted his father in the labors of the farm until September, 1862, when he enlisted in Company I, Twenty-first Wis. V. I., Capt. Smith commanding the company, which regiment was mustered in at Oshkosh, and attached to the army of the West. Mr. Augustin participated in the battles of Perryville, Ky. (October 8, 1862), and Stone River, Tenn., (January 1, 1863), at which latter he was taken prisoner. For three months he was confined in Libby Prison, and then paroled; rejoined his regiment at Murfreesboro, Tenn., and participated in all its subsequent battles up to that of Resaca, Ga., May 14, 1864, where he lost his left leg; in the spring of 1865 he was honorably discharged. Shortly after his return home he was married in Chicago, Ill., to Miss Helen McGogo, a native of the North of Ireland, born in 1838. Her parents, of whom she knows nothing excepting that they were farming people in Ireland, died when she was four years of age, and when she was fifteen she came to this country; the only relative she has any recollection of was a sister who lived in New Jersey. To this union were born five children, namely: Charles J., owner of the Glenwood Tribune, at Glenwood, Wis.,; William F.; George E., editor of the Saturday Evening Press; Robert A. and Thomas. In 1865 our subject came to Menasha, and in a small way embarked in mercantile business, in which he continued until the spring of 1884, when he disposed of the store; in the fall of 1883 he purchased his present paper, of which he has made an eminent success. In his political affiliations he is a stanch Republican, and has served on the county board, and as alderman from the First ward of his city; under President Harrison he was receiver of the United States Land Office at Menasha. Socially he is a member of Post No. 44, G.A.R., and he and his wife attend the services of the Congregational Church.
