Maryland Department Collection and State Library Resources

Genealogical Research in the Maryland Department


Before You Begin Your Library Research

Before coming to the library, try to identify facts, such as the spelling of names, relationships and dates. Talk to your relatives to see if they can provide any information you can use, perhaps in family bibles or previously researched family history.

You will want to know the following before you contact the library:

  • Which time period do I need to search?
  • What county or counties does my family come from?
  • What have I already found, or which documents do I already have?

Genealogical Resources in the Maryland Department Collection

Statewide Books
This portion of the collection includes books that cover the entire state of Maryland. These books are usually one of three types:

  • Indexes: alphabetical lists of names, subjects, etc., that point you to places you can find related information.  Researchers will find general indexes, indexes of vital records, wills, court and land records, church and cemetery records, as well as records from a specific institution, and more.
  • Bibliographies: listings of other books or articles that may be helpful in finding genealogical information. Many genealogy magazines and journals contain bibliographies of useful sources.
  • Directories: refer you to other locations that may have information on the person or institutions you are trying to find.

Individual Family Histories
Though not generally collected, there are a few hundred family histories in the Maryland Department. Most of these works are non-circulating; however, photocopying is permitted from all sources.

County Specific Books
Though the Maryland Department attempts to get many statewide resources, available information varies by county.

The following are some of the county-based genealogical resources in the Maryland Department:

  • County histories: especially useful in finding surnames and family homes
  • City directories: help you locate a person, family or business for a specific year or a span of years. Directories may provide a person's occupation, or listings of government agencies, houses of worship, and charitable institutions.
  • Telephone directories
  • Criss-cross directories -- or reverse telephone directories -- list residents by street address rather than by name
  • Indexes of marriage and death announcements in newspapers, including obituaries dating back to the early 18th century
  • Listings of interments from local cemeteries
  • Land patents
  • Yearbooks from high schools and colleges

Special Indexes
Many of the indexes in the Department contain genealogical information, and there are others that supplement this type of work very well. Index cards

  • Ephemera Collection: database which provides access to a collection of miscellany which may include, but is not limited to posters, letters, photographs, menus, programs and other items

Newspapers are a rich source of information for family research. You can find obituaries, death notices, marriage and birth announcements, and legal notices. Social and political events, disasters, and ship arrivals and departures may identify ancestors. Even advertisements provide valuable information on family businesses. The Maryland Department receives 23 subscriptions to Maryland newspapers and holds some historic newspapers.  However, the Library’s Periodicals Department houses most of our historic papers.

Biography, Query and Vertical Files
These files contain hundreds of thousands of cards that will direct you to sources in various formats, both in the Maryland Department and in other departments of the Library.

  • Query File: contains entries on places, events, institutions, businesses and, in some cases, people
  • Biography File: includes references to persons and families only

Maps can provide valuable clues when tracking ancestors. The Maryland Department's map collection includes over 2000 maps, dating from 1630-present. Maps show neighborhoods, businesses and the distance from home to a place of work or worship.  In Baltimore City, 19th century street maps identify ward numbers necessary in locating census enumerations. County maps show election districts for the same purpose.

Many Maryland county atlases, published in the late 19th and early 20th centuries, identify landowners, the approximate boundaries of their property, and election districts.

Sanborn fire insurance maps show characteristics like house numbers, names of businesses and water and sewer lines. They are available in the Department on microfilm, or through the Library’s databases. Our collection cover volumes produced from 1890 - the early 1980s for Maryland.
