The historical society was chartered in 1970 to preserve the history of Kendall County and to provide historical education for the county's residents. The Kendall County Historical Society has no paid staff, nor does it depend on support from any governmental agency. Operating income is derived from memberships, regular and memorial donations, events held at the Lyon Farm, fees for providing research material, the sale of books and other miscellaneous items. The everyday business of the organization is handled entirely by volunteers. Kendall County is located in the north central part of Illinois and was established in 1841.
