The history of Jewish-convert and crypto-Jewish communities in New Spain constitutes a crucial yet often overlooked chapter of Mexican genealogy. During the 16th and 17th centuries, thousands of families of Sephardic origin arrived in Mexican territory fleeing the Spanish and Portuguese Inquisition, settling primarily in northern regions such as Nuevo León, Coahuila, and Jalisco, as well as in the central part of the country. To preserve their lives and integrate into colonial society, many of these lineages adopted or modified their family names, choosing place names, elements of nature, or translations of Hebrew words that allowed them to keep their faith secret while outwardly practicing Catholicism.

In this genealogical and historical analysis, we explore 20 Mexican surnames of Sephardic Jewish origin that remain in use in millions of families today. We examine the historical context behind their adoption, the symbolism hidden within their meanings, and the migratory patterns these dynasties followed from the Iberian Peninsula to the provinces of New Spain. Many of these surnames are linked to specific trades, trees, Spanish cities, or Hispanicized variations of biblical names that survived the Inquisition and became fully integrated into the demographic landscape of modern Mexico.

If you are tracing your ancestors' history or researching Sephardic heritage in your family tree, this documentary breakdown offers precise information about the lineage and origin of your family's patrimony. Consult the complete list, examine your ancestors' roots, and discover if your surname carries the legacy of those crypto-Jewish communities that helped shape the identity and customs of various regions of Mexico.
