Illinois Maps

Several types of maps are useful for genealogists. Some give the historical background of the area; others show migration routes such as roads, rivers, and railroads. Topographical maps show physical and manmade features, such as creeks, hills, trails, and roads used as persons came to Illinois. Sometimes maps also include cemeteries and churches. Plat and land ownership maps, as well as other types of maps, are described in United States Maps. In the FamilySearch Catalog, atlases are listed in the Place Search. Remember to search each locality as a town, a county and as a state.

A county-by-county list of land ownership maps is:
