United States Maps Index

Historical maps of the United States offer critical context for genealogy, especially in a nation shaped by expansion, migration, and shifting boundaries. Early colonial maps, county atlases, and land plat maps reveal property ownership, settlement patterns, and administrative changes. Sanborn Fire Insurance maps detail urban structures down to individual buildings, while township and range maps clarify federal land divisions. Military surveys, postal route maps, and transportation maps also inform ancestor movements and local developments. Because many U.S. genealogical records are organized by county, maps help identify jurisdictions at specific times. Resources from the Library of Congress, state archives, and genealogical websites have made many historical maps accessible, anchoring family stories in geographic reality.
