History of Winnebago County
"When the first white settlers came into the county, and for some years thereafter, roving bands of Winnebago Indians made their temporary home within the limits of the county. At times there would be as many as one hundred living along the Lime Creek valley or about Coon Grove, and at other times there would be but a mere handful ... During the summer seasons they would cache their cooking utensils, leave their tepees standing and go northward into Minnesota to hunt and trap. At that time the Winnebago agency was located about forty miles north of Forest City." The Winnebago were removed after the Dakota War of 1862. Initial settlement was in the wooded eastern third of the county, with prairie and marshy areas in the west being settled after 1880. Early teachers in Winnebago County were required to be able to converse in the language of their pupils.
