Between 1837 and 1840, New York-born William M. Gray settled along the then-unnamed Grays Lake. Other farmers trickled into the area in the 1840s. The Grays moved to Iowa between 1851 and 1853. In 1880, the Wisconsin Central Railroad built a line from Fond du Lac, Wisconsin, to Chicago that passed by the east side of Grays Lake. In 1886, the railroad built a station at the intersection of what is now Seymour and Center. The village incorporated as Grays Lake in 1895.
Grayslake is one of Lake County's oldest communities. The Village offers numerous family-friendly events, including the annual Lake County Fair and the country's largest evening farmers market. Visitors also enjoy unique dining and shopping experiences in Grayslake's historic Downtown.
