Registro Civil del Estado de Sonora, México.

Record Description
This is a collection of civil registration records for Mexico. Records, such as birth, marriages, and deaths, are organized by state and then by municipality/city. Earlier records were handwritten in narrative style; later records were handwritten in formatted registers. The text of these records is in Spanish.

The civil registration records in Mexico are an excellent source for genealogical research after 1867. Important genealogical data can be found in these records, which may also include data of other family members to fill in another generation group.

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 civil registration wasn't strictly enforced in Mexico until 1867 and people did not always comply. For this reason, church registers must be used alongside the civil records. The civil records of Mexico have been preserved relatively well. Only some of the older registers may have some physical damage; however, in general they are in good condition to extract genealogical information

How to Use the Record
Begin your search by finding your ancestors in the index. Name indexes to births, marriages, and death make it possible to access a specific record quickly. Remember that these indexes may contain inaccuracies, such as altered spellings, misinterpretations, and optical character recognition errors if the information was scanned.

When searching the index it is helpful to know the following:


 * The place where the event occurred
 * The name and surname of the person
 * The approximate date of the event
 * The name of the parents or spouse

Use the locator information found in the index (such as page, entry, or certificate number) to locate your ancestors in the records. Compare the information in the record to what you already know about your ancestors to determine if this is the correct person. You may need to compare the information of more than one person to make this determination.

When you have located your ancestor’s record, carefully evaluate each piece of information given. These pieces of information may give you new biographical details that can lead you to other records about your ancestors. Add this new information to your records of each family.

For example:


 * Use the marriage date and place as the basis for compiling a new family group or for verifying existing information.
 * Use the birth date or age along with the place of birth of each partner to find a couple's birth records and parents' names.
 * Use the birth date or age along with the place of birth to find the family in census records.
 * Use the residence and names of the parents to locate church and land records.
 * Occupations listed can lead you to other types of records such as employment or military records.
 * Use the parents’ birth places to find former residences and to establish a migration pattern for the family.
 * The name of the officiator is a clue to their religion or area of residence in the county. However, ministers may have reported marriages performed in other counties.
 * Compile the marriage entries for every person who has the same surname as the bride or groom; this is especially helpful in rural areas or if the surname is unusual.
 * Continue to search the marriage records to identify children, siblings, parents, and other relatives of the bride and groom who may have married 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.
 * Use the marriage number to identify previous marriages.
 * When looking for a person who had a common name, look at all the entries for the name before deciding which is correct.

Keep in mind:


 * The information in church records is usually reliable, but depends upon the reliability of the informant.
 * Earlier records may not contain as much information as the records created after the late 1800.
 * There is also some variation in the information given from one record to another.

If you are unable to find the ancestors you are looking for, try the following:


 * Check for variant spellings of the surnames.
 * Check for a different index. There are often indexes at the beginning of each volume.
 * Search the indexes and records of nearby localities.
