A number of historic communities in Buchanan County once appeared on state maps, but no longer exist. Hamerville was located east of Brandon at the intersection of Highway 150. Today, the site is the location of three farmhouses. Vista, once located between Brandon and Independence, appeared on maps frequently until the 1950s. This site is not even accessed by paved road. Kier, between Fairbank and Littleton, appeared on many maps in the 19th century and early 20th century. The area is now settled by Amish. Several towns named Middlefield existed southeast of Winthrop, but none are populated today. Newtonville was located a few miles south of Monti. The houses at Castleville were later moved to Aurora. Wise, once located between Independence and Jesup just north of Highway 939, was a train-stop between the 1920s and the 1950s. Little remains at the site. Kiene was founded in 1911 between Quasqueton and Monti, but was empty by 1955. Few or even no houses remain at any of these sites.
