The town was first known as Crystal Ville. It was changed to Crystal Lake sometime before 1840. The area known today as downtown Crystal Lake was first called Dearborn and later, Nunda (pronounced locally as "Nun-day"), from an area in New York where many settlers originated. The village of Dearborn was founded in the 1850s after an extension of railroads through the area. The first train station was built in 1856, although it was pre-fabricated and shipped from Chicago on a flatcar. At that time, the main business district for the village of Crystal Lake was located on Virginia Street, about one mile (1.6 km) southwest of the railroad station. The railroad served to connect both the people and industries of Crystal Lake and Dearborn to Chicago and the rest of the country.
