Mexico Finding Town of Origin

Sometimes the most difficult part of researching your immigrant Mexican ancestor is locating their hometown. If your Hispanic ancestor came from Mexico to the United States, the following record types might provide that elusive clue to their place of origin.

Important Tips
Before you can begin to search in the records of Mexico you must find that one record that gives the name of his or her hometown. You must also know enough about the ancestor to positively identify him in the records. Dates (even if they are approximate), places, and familial connections are key to helping you decide if a person you find, who has the same name as your ancestor, really is your ancestor.


 * Do you know the name of his/her parents?
 * Do you know his/her birth, marriage, or death date or can you calculate an approximate range of years to search for his/her birth, marriage, or death?
 * Do you know the name of the spouse? Did they marry before or after coming to the United States?
 * Do you know the names of any of his/her siblings?


 * Do you know the names of any children born in Mexico?

Documents in the home
Often the document you need to pinpoint the place of origin of your Mexico ancestor is already found at home. These might include the following:


 * Birth certificates
 * Marriage certificates or licenses
 * Death certificates
 * Obituaries
 * Funeral cards
 * Journals
 * Photographs
 * Letters
 * Family Bible
 * Naturalization papers
 * Citizenship papers
 * Military service records

Emigration Questions to Ask Relatives
Find the oldest living relatives that you can and ask them:


 * 1) What do you know about our first ancestor to come from Mexico? (open-ended)
 * 2)  Have you ever heard mention of towns in Mexico where the family lived?
 * 3)  Do you have contact with any relatives in Mexico?
 * 4)  Do you have contact with other branches of the family in the U.S.?
 * 5)  When _____________ came from Mexico, did he travel with other family members?
 * 6)  Do you know when _________________ arrived?
 * 7)  Did _______________ever become a citizen?
 * 8)  Did_________________fight in World War I or II?
 * 9)  When they first came, were there already family members here who they joined?
 * 10)  Did_______________ever mention their parents in Mexico?
 * 11)  Do you have any old letters or postcards from Mexico family?
 * 12)  Do you have any pictures of family members in Mexico?

Make Sure You Found the Correct Entry for Your Ancestor

 * Make sure the person you found in Mexican records left Mexico. Look for them in marriage and death records of the same vicinity. See whether they have children a generation later in the vicinity. These things prove they remained in Mexico and would rule them out as your ancestor.
 * Match any other relationships. If you already know the parents' names, spouse's name, and/or siblings' names, make sure they match the parents' names, spouse's name, and/or siblings' names of the person you are considering in the Mexican records. The parents and grandparents will usually be listed in birth records found in church records or civil records. Search for siblings' birth records and any marriage before leaving Mexico in the same index.
 * Study all available entries for that name born at the same approximate time, not just the first possible match you see.
 * Consider the coverage of the database you are using. Does it cover all of Mexico? Or could there be many other records not covered that could hold your ancestor's record. For example, if the database is for just one province, there are 110 other provinces which could have your ancestor's record.
 * Make sure the details you have learned about the person after they immigrate have no discrepancies with the person you found in Mexican records.

Mexico Records Databases to Try

 * Mexico Guided Research
 * Mexico Civil Registration, government birth, marriage, and death records are available online for many provinces from the early 1800s to the early or mid-1900s. These records can name grandparents in addition to parents, and towns for residence and/or birth for both.
 * There are several Mexico Church Records online.
 * See Mexico Emigration and Immigration for records of Mexicans immigrating, including some online digitized records and indexes.
 * See Mexico Online Genealogy Records for other databases that might hold clues.

Records of the Country of Destination

 * Church Records: If your ancestor immigrated to a European or a South American/Hispanic country, church records can be detailed enough to identify a former residence or birthplace in the home country. These countries, unlike the United States, had state churches. In many countries, these state churches were used by the country to keep birth, marriage, and death records. Even though your ancestor was born in his former country, he may have married, and certainly died in his new country. Marriage and death records can state birthplace.
 * Civil Registration: Eventually, most governments began keeping birth, marriage, and death records. These tend to be quite detailed. Again, if your ancestor was possibly married and certainly died in their new country, those records can state birthplace.
 * Citizenship Records: If your ancestor became a full citizen, those records probably name birthplace and former residence.
 * Online Genealogy Records: See Online Genealogy Records by Location and find the online genealogy record page for your country to see other indexed collections that can be consulted.

Vital Records
Understand that any birth, marriage, or death certificate gives information about other people besides the primary person it is about
 * 1) It is important to remember that a birth certificate for a child might tell it's parents' birthplaces.
 * 2) Marriage certificates might name birth dates and places of the bride and groom. They might also give the names and birth places of the parents of the bride and groom.
 * 3) Death certificates are very important.  Birth and marriage certificates might not have kept by a state during the earlier years of your ancestor's life.  There is a greater chance that your ancestor died after detailed record-keeping began. Death certificates frequently state birth date and place.  They also state the names of parents and their birth places.


 * There are wiki articles giving details on how to find vital records o each state. You can select the state of interest and the record (birth, marriage, or death) from this list: How-To Articles.

Naturalization Records

 * Naturalization records may also list an ancestor’s birth place.
 * Prior to 1906 any U.S. court could naturalize foreigners. Many pre-1900 records only list “Mexicop” as the country of citizenship; however, there are notable exceptions, so these records should be checked routinely.
 * The process involved two sets of papers: a declaration of intention to become a U.S. citizen, and a petition filed some time later.
 * Beginning in 1906, naturalization records became more detailed, as the responsibility shifted to the Federal government.
