The Roscoe area was first settled along the Rock River in 1835, and named for one of its early settlers. As Roscoe grew, it became a stagecoach stop for travelers heading west. By the first decade of the 20th Century, Roscoe continued its growth along the interurban railroad, with daily service being supplied by the Rockford, Beloit & Janesville Railway. The advent of the automobile eventually forced the interurban out of business, with the last car passing through Roscoe in October 1930.
The Village of Roscoe was incorporated in 1965. Today, Roscoe continues its growth at a steady pace through residential and commercial developments. The Village of Roscoe and the Stateline Area are the fastest growing areas in Winnebago County. Convenient location, excellent schools, community opportunities for employment, recreation, shopping and a beautiful and safe place to live and work is why this region enjoys continued growth.
