From "History of La Crosse County, Wisconsin", 1881, p. 761. City of La Crosse JOHN HEILLER, cooper and stockholder in the La Crosse Co-Operative Barrel Manufacturing Company, was born in Clayton Co., Iowa, in 1851, son of William Heiller, who died in 1869. Mr. Heiller learned his trade in his native place; came to La Crosse in April, 1880, and purchased stock in the present company the following fall. He was married in 1874, in Clayton, Iowa, to Miss Matilda Friend, and has two children - Fannie Sophia and Lottie Anna. [I am not related to this family and have no further information.
