Etymology - Origin of County Name

Dunn County was named in honor of Charles Dunn, first chief justice of Wisconsin Territory -- Gannett, Place Names, p. 98.

Charles Dunn (1799-1872) was born in Kentucky, where he studied law, but was admitted to the bar (1820) in Illinois. During his residence in that state he served as captain in the Black Hawk War, wherein he was accidentally shot by a sentinel. In 1829 he assisted in laying out the plat of Chicago. Appointed chief justice of Wisconsin Territory in 1836, he served throughout the Territorial era, also acting as member of the second State constitutional convention. In 1852-53 he was State senator from Lafayette County, and died at his home at Belmont (now Leslie), in that county.

County History

From: Handbook of Wisconsin by S. Silas, 1855
pg. 68-69

A new County, lying on the Chippewa and Red Cedar Rivers, not thickly settled, well watered and generally good soil, having a due proportion of timber, prairie and openings. Hay River, in the northern part of the County, a branch of Red Cedar, has pine upon its banks, and saw mills are now running. Pine is also cut on the Eau Galle. The resources of this County have not yet begun to be developed.

Most of the land is yet in the hands of Government, and affords rare chance to th immigrant for investment. Part of the County lies in Willow River and part in La Crosse Land Districts.

Kansas, a new village on Lake Pepin, is the largest place, and already contains a population of 300.


According to the U.S. Census Bureau, the county has a total area of 864 square miles (2,238 kmē), of which, 852 square miles (2,207 kmē) of it is land and 12 square miles (31 kmē) of it (1.38%) is water.

The history of our nation was a prolonged struggle to define the relative roles and powers of our governments: federal, state, and local. And the names given the counties, our most locally based jurisdictions, reflects the "characteristic features of this country!"
