Champaign County, IL
History
Champaign County was organized in 1833, having been previously a part of Vermilion County. The county and county seat were named for Champaign County, Ohio and Urbana, Ohio respectively, the homeplace of the Illinois legislator who sponsored the bill to create the county. The development of the county was greatly furthered by the arrival of the Chicago Branch of the Illinois Central Railroad, and even more by the establishment of the land-grant university. Later, the county also got an airport and a mass transit district.http://en.wikipedia.org/wiki/Champaign_County,_Illinois
