Maps are an important source to locate the places where your ancestors lived. They help you see the neighboring towns and geographic features of the area from which your ancestor came.

Maps are also helpful in locating places, parishes, geographical features, transportation routes, and proximities to other towns. Historical maps are especially useful for understanding boundary changes.

Maps are published individually or as an atlas, which is a bound collection of maps. Maps may also be included in gazetteers, guidebooks, local histories, historical geographies, encyclopedias, and history texts.

Using Maps

Maps must be used carefully for several reasons:

  • There are often several places with the same name. For example, there are over 50 towns throughout the various states of Mexico that begin with the name Dolores.
  • The spelling and even names of some towns may have changed since your ancestor lived there. For example, the town presently known as Arroyo Seco was formerly named El Rincón, in the state of Sonora.
  • Place-names are often misspelled in English sources. Difficult names may have been shortened and important diacritic marks omitted.
  • Political boundaries are not clearly indicated on all maps.

Finding the Specific Town on the Map

To successfully research maps from Mexico, you must identify the town where your ancestor lived. Because there are several towns that have the same name, you may need some additional information before you can locate the correct town on a map. You will be more successful in identifying the town on a map if you have some information about the town. Using gazetteers and other such sources to identify the municipio and district your ancestor’s town was in will distinguish it from other towns of the same name and help you locate it on a map. See the Mexico Gazetteers article for more information.

Types of Maps

Different types of maps help you in different ways, for example:

  • Historical atlases describe the growth and development of countries, showing boundaries, migration routes, settlement patterns, military campaigns, and other historical information.
  • Road atlases are useful because of the detail they provide.
  • Other types of maps include: parish maps, state maps, tourist maps, topographical maps, and air navigation maps. City maps are extremely helpful when researching in large cities such as Mexico City.
