Choosing the Best Maryland Map – If you have a large source of maps to choose from, try starting with the area where your ancestors resided and looking for the maps with the most detail.  You can determine a lot by seeing if the area was still rural or more developed, and how far it was to the nearest city.  This can shed light on your family’s lifestyle and occupation. Were they farmers who lived in the country, or merchants who traveled often to a nearby city?  A map can give you an idea of what occupations were possible.

This can make it difficult to understand where your ancestors’ information is kept.

Because Maryland historic maps were usually commissioned by the county seat, they often display information about the county, including town names. Reading a Maryland map from the time period you are researching can help tremendously in solving these problems by leading you to the correct town records. It can also give you other leads, such as the location of city directories or old post offices in Maryland.

Some Historical Maps of Maryland can indicate who owned specific property in the state and which towns held the county seat at the time. This information is a valuable starting point for your research pointing you to the right location of records.
