At its height in 1519, the Aztec Empire was a multi-ethnic, multi-lingual realm stretching more than 80,000 square miles and ruling over 15 million people. But, for all its strength and breadth, the Aztec Empire failed to conquer several regions that represented “independent enclaves” within their vast dominion. One of those enclaves contained the people then known as the Tlapaneco (now known as Méphaa). Their enclave was known as Yopitzinco.

The saga of Álvar Núñez Cabeza de Vaca, as recorded in his own narratives, serves as one of the most fascinating chronicles of European exploration in North America and offers one of the earliest and most detailed European perspectives on indigenous life and landscapes in the 16th century.

Mesoamerica was filled with hundreds of cultures, all interacting with each other sometimes as foes fighting for power or as allies joining a common goal or beneficial arrangement. In the case of the Aztecs, their biggest ally was the Acolhuas of Texcoco.

For at least 15,000 years, the people of the Americas – for the most part – had been isolated from the entire Old World (which included Europe, Asia and Africa). This meant that many diseases which had regularly plagued the Old World were never experienced by the Native American populations.

Many Yaquis came to Arizona either alone, in small family groups, or as unrelated groups who shared a common heritage. The Yaquis followed the Southern Pacific Railroad tracks establishing the first Yaqui communities in the Tucson area. Many continued to journey north, following the railroad tracks and establishing communities in Marana, Eloy, Sacaton, Phoenix, Yuma.

Náhuatl is one of the most spoken indigenous languages in the Americas with over 1.7 million speakers and is part of the Uto-Aztecan (UA) family language. A language family that historically spanned from the US state of Idaho down to Northern Costa Rica. This family contains a variety of different languages that all came from a common ancestor thousands of years ago. Over the years various migrations occurred and groups eventually diverged from each other and started to become their own independent culture and language.

Tracing an indigenous family across the generations is challenging, but it is definitely possible when the records you are exploring are indexed. In order to provide your links to the past, you want to find as many direct bloodline ancestors as possible, but it is good to also find the records of collateral ancestors [siblings of your ancestors]. Sometimes, the records of siblings can be useful in assembling your lineage. The baptism of the sibling may be more readable and more detailed than the baptism of your direct ancestor.

Doing research on one’s indigenous roots in Guanajuato can be a challenge. In the Eighteenth Century, many Indigenous People simply did not have surnames. Instead, they were likely to have two given names. Other Indigenous People would carry a Spanish surname for a period of time and then discard it in favor of another surname, or none at all.

Today, Jalisco is the seventh largest state of Mexico with the fourth largest population. Its diverse terrain gave rise to an incredible diversity of tribal groups. Professor Eric Van Young has noted that the area of central Jalisco “supported relatively dense populations” and a “considerable ethnolinguistic variety prevailed within a fairly small geographic area.” But thanks to the Spanish conquest, Dr. Van Young also notes that “the extensive and deep- running mestizaje of the area has meant that at any time much beyond the close of the colonial period the history of the native peoples has been progressively interwoven with (or submerged in) that of non-native groups.”

Exploring the genealogy of an Indigenous family in Ayutla, Jalisco, throughout the 17th and 18th centuries highlights the vital role of post-1800 baptism records from Jalisco in advancing genealogical research. Ayutla, situated within Jalisco, was home to Indigenous communities fluent in Náhuatl and Cuyuteco languages. This journey reveals intriguing patterns, where some Indigenous individuals maintained consistent surnames across generations, while others embraced surnames solely upon marriage or the birth of their children.

Researching the ancestry of Indigenous families in historical Jalisco, Zacatecas, and Aguascalientes presents unique challenges. During the 17th and 18th centuries, it was common for many Indigenous People not to have consistent surnames. This inconsistency could be attributed to various factors, including changes in employment or land ownership. Unlike the Spanish who typically maintained a strong attachment to their surnames, Indigenous People often adapted or altered their surnames, sometimes opting not to use one at all. This fluid approach to naming makes tracing lineage a complex but fascinating endeavor.

Tracing an indigenous family backwards in time can be an interesting challenge for the Jalisco Researcher. Many Indigenous people in the 17th and 18th Century Jalisco, Zacatecas and Aguascalientes did not even have surnames. Or they had surnames that changed from generation to the generation, possibly depending on their employer or owner of the land they lived on. In many areas, Indigenous people – for very understandable reasons – did not have the same loyalty to their surnames as Spaniards did. Hence, one surname might be discarded for another surname… or no surname at all.

According to Aztec legends, seven Náhuatl-speaking tribes migrated from the northwest to what is now central Mexico. One of these tribes were the Tlaxcalans. Over time, from the 1420s until 1519, another Náhuatl tribe came to dominate most of the region and developed the powerful Aztec Empire by subduing neighboring city-states.

By 1519, the Aztec Empire had become a multi-ethnic, multi-lingual realm stretching more than 80,000 square miles throughout central and southern Mexico. Living to the east of the Aztec capital Tenochtitlán, the Tlaxcalans inhabited about 200 semi-autonomous villages.

The year 2020 marked the 499th anniversary of the first Tlaxcalan migration of the 16th century to other parts of Mexico. Starting on June 6, 1591, selected families from Tlaxcala left their native soil to populate various locations in central and northern Mexico.

The Tlaxcalans had first assisted the Spaniards in destroying the mighty Aztec Empire in an extended campaign (1519-1521). As a reward, the Spaniards awarded the Tlaxcalans special rights and privileges. In fact, the Spanish-Tlaxcalan alliance soon evolved into a “stable, institutionalized pact” in which “Tlaxcala became a state within the empire.”

Today, more than 7 million of Mexico’s 126 million people speak 364 Indian linguistic variants (dialects), but almost 90% of those people are bilingual, speaking both Spanish and an Indigenous language. Those who do not speak Spanish are called monolingual.

When the Spaniards first reached Sinaloa and Sonora in 1531, they found indigenous people living along the coastal region. Speaking eighteen closely related dialects, the Cáhita peoples of Sinaloa and Sonora numbered about 115,000 and were the most numerous of any single language group in northern Mexico. The Spaniards called them "ranchería people.“

Mexico’s 2020 Population and Housing Census was conducted in March 2020. More than 147,000 interviewers traveled the nearly two million square kilometers of the national territory, visiting all Mexican households to obtain information about the demographic, socioeconomic and cultural characteristics of the people of each state.

Coahuila de Zaragoza – the third largest state of Mexico – was inhabited by six nomadic indigenous groups when the Spaniards arrived in the late Sixteenth Century: The Tobosos, Irritilas, Coahuiltecans, Rayados, Chisos and Guachichiles. The Coahuiltecans occupied a considerable part of what is now eastern Coahuila, but also occupied a large portion of northeastern Mexico and southern Texas. They were made up of hundreds of small autonomous bands of hunter-gatherers.

The following tables contain information of the native people of the Spanish jurisdictions in Nueva Galicia, Nueva Vizcaya, Sonora and Sinaloa. These extracts primarily contain information about the indigenous groups occupying these areas at the time of the Spanish contact, the year of which varies from one place to another. However, Peter Gerhard’s book contains a wealth of local information, and it is highly recommended that interested researchers purchase the book to have access to all the information provided.

The Sierra Madre Occidental Mountains run from south of the Arizona-Sonora border southeast through eastern Sonora, western Chihuahua, Sinaloa, Durango, Zacatecas, Jalisco and farther south. The Sierra Madre Oriental Mountains run parallel to the Sierra Madre Occidental range on the eastern side of the country.
