How Neillsville came to be
From Wikipedia’s history of Neillsville.
The Ojibwe were the earliest known residents of the Neillsville area. The first settlers of European descent in the area were James O'Neill and his party, who arrived around 1845, looking for a location to build a sawmill along the Black River. The city was named in honor of O'Neill, as was O'Neill Creek, which runs through the center of the city and drains into the Black River.
In 1854, O’Neill's Mill, as Neillsville was originally called, was selected as the county seat of Clark County. Neillsville was platted on April 14, 1855, and incorporated in April 1882.
A Winnebago Indian boarding school was operated by the Evangelical and Reformed Church on the west side of Neillsville from 1921 to 1957.
