Mexico, Sonora, Civil Registration - FamilySearch Historical Records

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

They are records of births, marriages, and deaths and 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 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 records can be used alongside the civil records.
