Facts About Green County, WI

The county was created in 1837 from the Wisconsin Territory. When in December 1837, a new county was to be split off from the over-large Iowa CountyWilliam Boyles of Monroe, as the Representative of the area, was allowed to choose a name. He chose Green County, after the verdant color of the vegetation there. Another member suggested that it be modified to "Greene" after General Nathanael Greene, who commanded the Southern Campaign in the American Revolutionary War but Boyles insisted on his original choice. The story that it was named for General Greene still persists in some circles.
