Mexico Finding Town of Origin

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

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?

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.
