For many years, Aguascalientes and Nueva Galicia researchers have agreed that one branch of Moctezuma’s descendants ended up in Aguascalientes. However, the paper evidence for this theory has been difficult to assemble. And, at this point in time, there are still some gaps. It is believed that the researchers Guillermo Tovar de Teresa and Mariano Gonzalez-Leal have put together more detailed analysis on this lineage, but at this time, we will present what we have, which present parts of the picture.

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 Mexican state of Aguascalientes (“Hot Waters”) is located in central Mexico. Surrounded by Zacatecas (on the north and west) and by Jalisco (on the south and east), Aguascalientes occupies 5,589 square kilometers, corresponding to only 0.3% of the Mexico’s surface area. Although it is one of the smallest Mexican states, Aguascalientes holds a position of great importance in the Mexican Republic, in large part because of its strategic location within the country. With its textile, electronics and auto parts industries, Aguascalientes represents an integral part of the Mexican economy.

The State of Aguascalientes, located in central Mexico, is one of the smallest states in the Mexican Republic. Sharing its borders with Jalisco (on the south) and Zacatecas (on the north, west and east), Aguascalientes occupies a total of 5,616 square kilometers (2,168 square miles), which represents only 0.3% of Mexico’s national territory and is the twenty-eighth largest state in terms of area. Politically, Aguascalientes is divided into eleven municipios.

If your ancestors are from Zacatecas, Guanajuato, Aguascalientes, Jalisco or San Luis Potosí, it is likely that you are descended from the indigenous peoples who inhabited these areas before the Spaniards arrived from the south. The historian Eric Van Young of the University of California at San Diego has called this area, the “the Center-West Region” of Mexico. This cultural region, according to Dr. Van Young, amounts to about one-tenth of Mexico’s present-day national territory.

Origins in Santander

The surname Rubalcaba (also spelled Robalcava or Ruvalcaba) is known to have originated in the Mountains of Santander, with branches of the surname radiating from Medina de Cudeyo, Liérganes and Navajeda, three locations that are presently located in eastern Cantabria (northern Spain). Today, Cantabria is considered an autonomous area with Santander as its capital. It is bordered on the east by the Basque Autonomous Community, on the south by Castile and León (the provinces of León, Palencia and Burgos), on the west by Asturias and on the north by the Cantabrian Sea.

The following presentation offers suggestions for tracing your Mexican ancestors back to Spain or Portugal. Although we offer research suggestions and show the reader resources to locate ancestors from the Iberian Peninsula, it is important to state the following:

The surname Orozco (or Orosco) is a surname that has been prominent throughout both Spain and Mexico over the last few centuries. According to Richard D. Woods and Grace Alvarez-Altman, “Spanish Surnames in the Southwestern United States: A Dictionary,” two elements form this surname: “oros” which means holly tree and the suffix “-ko” which suggests place. Orozco therefore means place of the holly trees. Orozco is also believed to have been derived from the Latin word “orosius” – the son of bringer of wisdom.

Nueva Galicia’s Indigenous People: Established in 1548, the Spanish province of Nueva Galicia embraced 180,000 kilometers and included most of present-day Jalisco, Nayarit, Aguascalientes and Zacatecas.
