Mexico, Coahuila, Civil Registration - FamilySearch Historical Records

What is in This Collection?
This collection of civil records for Coahuila covers the inclusive years of 1861 to 1998.

This is a collection of civil registration records for Mexican state of Coahuila. It covers the years 1861 to 1998. Records, such as birth, marriages, and deaths, are organized by state and then by municipality/city. The earlier records were handwritten in narrative style and later these records were handwritten in formatted registers.

Civil records in Mexico cover about 90 to 95% of the population. Beginning in 1859, the Mexican government began requiring births, marriages, and deaths to be recorded by civil authorities on a municipality/district level. Although these records are a great source of genealogical information, they are not complete as people did not always comply, and civil registration wasn't strictly enforced in Mexico until 1867. For this reason, church registers should be used alongside the civil records. The civil records of Mexico have been preserved relatively well. Some of the older registers may have some physical damage, but in general the records are in good condition to find genealogical information.

I Found Who I Was Looking For, What Now?

 * Use the birth date or age along with the place of birth to find the family in 1930, Mexico National Census.
 * Use the residence and names of the parents to locate church records.
 * Use the parents' birth places to find former residences and to establish a migration pattern for the family.
 * Compile information for every person who has the same surname as your ancestor; this is especially helpful in rural areas or if the surname is unusual.
 * Continue to search the records to identify children, siblings, parents, and other relatives in the same county or nearby. This can help you identify other generations of your family or even the second marriage of a parent. Repeat this process for each new generation you identify.

I Can’t Find Who I’m Looking For, What Now?

 * New information is constantly being indexed, microfilmed or updated. Periodically check back and see if your ancestor’s records have been added.  You can see if the area you’ve been looking in has been recently updated by going to Historical Records Collections and notice the asterisk for recently added or updated records.
 * Try looking through records in the surrounding localities. Durango is to the southwest, Chihuahua to the west, Texas to the north, Nuevo León to the east, and Zacatecas to the south.
 * Vary the search terms. For example, search by either the given name or surname to return broader list of possible candidates which can then be examined for matches. Or try expanding the date range; this is especially useful in searching baptismal records, as it was not unusual for a child to be baptized weeks or even months after birth.
 * Check for variants of given names, surnames, and place names. Transcription errors could occur in any handwritten record; also, it was not uncommon for an individual be listed under a nickname or an abbreviation of their name. Click here for a list of Spanish name abbreviations
