There is a place to do Mexican Map Search, Mapoteca Manuel Orozco y Berra and it contains a collection of maps that can help you find old maps of Mexico, its states, and cities.
Maps play an important role when it comes to Mexican genealogical research. They help us identify long gone haciendas, towns, and even cities, as is the case with Guerrero (Revilla), Tamaulipas. Not to mention they also help us locate the ones whose name has been changed.
Manuel Orozco y Berra (June 8, 1816 – January 27, 1881) was a Mexican historian and a member of the Mexican Academy of Language. He was born and died in Mexico City. Some digital maps from his collection have been digitized and are available online on a website provided by the Secretary of Agricultura, Ganaderia, Desarrollo Rural, Pesca y Alimentacion.
