Historic Land Ownership Maps and Atlases Online

Historic land ownership maps and county atlases show who owned land in a given area at a given time. Also displayed are towns, churches, cemeteries, schools, railroads, businesses, and natural land features. Land ownership maps make it easy to view the location and shape of an ancestor's land or farm at a particular point of time, plus its relationship to the land and locations of relatives, friends, and neighbors.

Land ownership maps are available online from a variety of resources, including subscription genealogy sites, University map collections, sources for digitized historic books, and locality-based websites hosted by individuals, genealogical and historical societies, and local libraries. Below you'll find a selected list of online resources for locating historic landowner and cadastral maps online, but you can find even more by entering search terms such as county atlas, cadastral map, landowner map, the name of a map publisher (i.e. F. W. Beers), etc. into your favorite search engine.
