April 2012 Now What? Q&A: Mexican and Early US Southwest Research
Expert answers on researching ancestors in Mexico and the early American Southwest.

Q. Where can I find genealogy records for Mexico, including the era when parts of the Southwestern United States were in Mexico?
A. The two best sources of Mexican genealogical information are church records and civil registrations. Before 1859, most records were kept on the parish level, known as registros parroquiales (parish registers). These included baptisms (bautismos), marriages (matrimonies), deaths (defunciones) and burials (entierros), and often covered not just one individual but two or three generations of the family. The Family History Library (FHL) has microfilmed most Mexican church records prior to 1930, and some are now among the Mexican collections online.
