Maps of Maryland

Most historical maps of Maryland were published in atlases. Within the atlases are historical maps, illustrations, and histories many of which contain family names ideal for genealogical research.

In 1634, the colony of Maryland was founded. The State of Maryland was created as the 7th state on April 28, 1788. States bordering Maryland  are DelawareMarylandVirginiaWest Virginia and Washington, District of Columbia.

Several types of maps are useful for genealogists. The Maryland Department of Natural Resources, Maryland Geological Survey features county topographical maps for Maryland that have been reprinted.

The Maryland State Archives also holds a large collection of plats, atlases, and maps for the state. Many of those maps have tract and owner indexes available as well.

The Maryland Historical Society has a large collection of maps on file as well. Most counties also have historical societies and collections that include useful county maps, some of which have been published.
