San Luis Potosí, Mexico Genealogy

Guide to State of San Luis Potosí ancestry, family history and genealogy: birth records, marriage records, death records, census records, parish registers, and military records.

'''Most of your genealogical research for San Luis Potosi will be in two main record types: civil registration and church records. This article will teach you methods for locating and searching these two record groups.'''

History
In 1592, gold and silver deposits were discovered in San Luis Potosi which triggered the establishment of the state. Spanish miners established the first town known as “San Luis de Mezquitique”, modern location of the capital San Luis Potosí. The first Constitution of San Luis Potosí was then written on October 16, 1826, and this was in effect until 1835 when Congress proclaimed it centralist. At this point, local legislatures disappeared and state governors were appointed by the central government. The state participation in the Mexican–American War in the years of 1846-1847 gave it the name "San Luis de la Patria", Saint Louis of the Motherland, for haven contributed important leaders and ideas during the struggle with the United States. During the Reform War, state involvement was very prominent. 

How to Find the Town of Origin in Mexico
To search the records effectively, you need to know the town in Mexico where your ancestor lived. For a checklist of sources to search for that information, use Mexico Locating Place of Origin. Also, see these two online classes:

 * U.S. Hispanic Immigration

Civil Registration

 * Civil registration records are government records covering birth, marriage, and death. They are an excellent source of names, dates, places, and relationships.


 * Civil authorities began registering births, marriages, and deaths in 1859, and most individuals who lived in Mexico after 1867 are recorded. Because the records cover such a large percentage of the population, they are extremely important sources for genealogical research in Mexico. Initially, the Mexican populace, accustomed to registering its vital events with the local parish church, opposed the register. It was not until the republic was restored in 1867 that civil registration was vigorously enforced.

Church Records
Although civil registration records are an important source for genealogical research in Mexico, many births, marriages, and deaths were never recorded by civil authorities; therefore, you must use church records to supplement this genealogical source.

The vast majority of Mexicans were Catholic and were registered in entries for baptisms, marriages, deaths, and burials in the local church records. Often two and sometimes three generations are indicated in the registers, with personal information on the family. Church records are the main source prior to 1850, when civil registration began. After this date one should search in both church and civil records, since there may be information in one record that does not appear in the other. For instance, the church records may only list the godparents, while the civil records may list the grandparents.

Tips for finding your ancestor in the records

 * Births were usually reported within a few days of the birth by the father of the child, a neighbor, or the midwife. A search for a birth record should begin with the known date of birth and then searching forward in time, day by day, until the record is found. It might be found within a few days of the actual birth date, but in some instances, it might be weeks or months later. Birth, marriage, and death records are often indexed by given name or surname.
 * The Catholic Church continued keeping records after the creation of the civil registration in 1859. Therefore two types of records are available for the marriages. Be sure to search both records. With the separation of church and state in Mexico, formalized by the 1917 constitution, civil authorities determined that for couples to be legally married they had to be married by the state. Because of the close affinity of the Catholic Church and the state authorities, this rule was not always followed, and church weddings were accepted by the state. Normally, however, couples were married by civil authorities prior to a church wedding. On rare occasions they were married civilly after a church wedding.
 * Some municipios are small and therefore only have one civil registration office, but there are other larger municipios that have several sub civil registration offices that report to the main municipio office.
 * Death records can be particularly helpful for people who may not have had a civil birth or marriage record but died during the period when civil registration had begun.

Search Strategy

 * Search for the relative or ancestor you selected. When you find his birth record, search for the births of his brothers and sisters.
 * Next, search for the marriage of his parents. The marriage record will have information that will often help you find the birth records of the parents.
 * You can estimate the ages of the parents and determine a birth year to search for their birth records.
 * Search the death registers for all known family members.
 * Repeat this process for both the father and the mother, starting with their birth records, then their siblings' births, then their parents' marriages, and so on.
 * If earlier generations (parents, grandparents, etc.) do not appear in the records, search neighboring parishes.
