First Steps

In order to begin tracing your roots in Mexico, it is vital that you have an exact place since most records were kept on a local level. For ecclesiastical records, the common level of jurisdiction is the parish, while civil jurisdiction is found on the municipio level. If your ancestors immigrated to the United States or another country, then you will first need to begin looking in the records of that country. For immigrants to the U.S., here are some helpful tips that can be of assistance to you in finding the ancestor’s exact place of origin:

Family Records

  • Communicate with other relatives who may remember details about your family.
  • Search for family documents such as birth, marriage, death or church christening and confirmation certificates.

Vital Records

  • Death and marriage records from the U.S. may list an exact place of birth for an immigrant.
  • Birth records of an immigrant’s children may also provide this information.

Naturalization Papers

  • Typically, U.S. Naturalization records after 1890 list an immigrant’s exact place of birth.

Mexican Border Crossing Records

  • These records are indexed on While many immigrants from Mexico are not recorded, and the records are in poor condition, this source is still a very good resource to check. The index will supply an immigrant’s last place of residence, which was often their place of birth as well.
