Naming Conventions:

Individuals use both maternal and paternal surnames. The paternal surname traditionally comes first

When a woman marries she keeps her full name. She may add her husband’s paternal surname

  • Look for a name following de, de la or del
  • Example Mary Jones Smith de Brian:
    • Jones is her mother’s surname
    • Smith is her father’s surname
    • Brian is her husband’s paternal surname

Women traditionally kept their maiden names when they married. Children took on both the father’s and mother’s surnames, in that order

  • This allows a researcher to be able to predict what the parent’s surnames are
  • Hint: Search by the paternal surname first (the first surname)
Civil Records

The Mexican Civil Registration Office (Registro Civil) keeps vital records of births, marriages and deaths since July, 1859

Prior to the restoration of the Mexican republic in 1867 compliance was slow. Therefore, check both civil registration and parish records for these years

These records can be found through the Family History Library or Family History Centers
