Among the well known citizens of Jackson county was William Mohlenbrock, who immigrated to the United States in 1859, coming directly to Illinois, and located in Red Bud, Randolph county. In 1861, loyal to his adopted country, he enlisted in Company C, Ninth Illinois Volunteer Infantry, and for four years did service in the army. In 1866 he settled at Campbell Hill, and was here extensively engaged in mercantile pursuits until his death, which occurred April 16, 1898. He was a man of great business enterprise and judgment, and was largely influential in building up the interests of the city, which he served as mayor several years. He founded the milling company which bears his name, and took especial pride and pleasure in advancing the cause of education,, serving as an active and valued member of the school board for many years. Fraternally he belonged to the A. F. and A. M. and to the G. A. R.
He married while in Red Bud Minna Kroemer, a daughter of Conrad Kroemer, a Randolph county farmer, and to them were born nine children: Malte, Charles, Eva, Fortis, Eric, Haydee, Osser, Herman and Ludwig. Charles and Eric are deceased.
