For Identifying Places[edit | edit source]

In order to access the records of our ancestors it is important to know who created the records and where they are kept. The knowledge of jurisdictions, civil and ecclesiastical, for the places where our ancestors lived will help you to know where they might be kept and which entity, governmental or religious, created them. The following websites will aid you in identifying jurisdictions. 

Gazetteers or Diccionarios geográficos

These can be useful for identifying municipalities. Civil registration records are one example of a vital record that would be created by municipalities. The most commonly used version for Mexico is the Diccionario geográfico, histórico y biográfico de los Estados Unidos Mexicanos by Antonio García Cubas.

There are two different websites with digital versions of the same book

Church Directories – Directorios eclesiásticos
