What is in the Collection?
This collection of civil records for Sonora covers the years 1861 to 1995.

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. These records are written 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 percent 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

The Mexican civil registration was created to record the vital events of birth, marriage, death, and other civil events, which would determine and prove the civil status, existence, and condition of the population.

The civil registration records of Mexico are a reliable source for doing genealogical research.
