Last Names of Nuevo Leon

This 517-page book presents six generations of documented descendants of Juan de Olivares and Juana de Treviño, two foundational figures in the early history of Nuevo León. Their descendants can also be found in CoahuilaTamaulipas, and Texas.

Who Was Juan de Olivares?

While Juan’s place of birth remains a mystery, records suggest he was born between 1595 and 1599. His name first appears in the archives of El Nuevo Reyno de León (now Nuevo León, Mexico) in 1624. A key historical document reveals that by 1619, he had already entered the region and was actively defending it with his servants and weapons. This service was acknowledged by Captain Diego Rodríguez, further establishing Juan's role in the region’s early development.

He is widely recognized as the progenitor of the Olivares surname in northeastern Mexico and South Texas.

His Life and Legacy

Juan played an active role in the legal and social life of the colony. Surviving archival records from Monterrey show him involved in numerous legal proceedings, often as a witness or in defense of his property rights. In 1635, with land granted by Governor Martín de Zavala, he founded the Hacienda de San Antonio in the Pesquería region.

Although the names of his parents remain unknown, we know that Juan married Juana de Treviño, daughter of Alonso de Treviño, sometime after 1626. Several marriage dispensations involving their descendants confirm this connection. Unfortunately, Juana’s mother's name has not survived in any known records.

Their Children

Juan and Juana had at least eight children: Beatriz, Bartolomé, José, Diego, Blas, Juan, Juana, Anastacia, and Alonso.

Juan de Olivares passed away in Monterrey on or before October 20, 1669, the date of his burial.

About the Book

This book documents six generations of their descendants, covering the period from the mid-1600s through the late 1800s. While I have identified over 16,000 descendants of Juan de Olivares and Juana de Treviño, only a portion of them is included in this volume.

Keep in mind, this book as all my others are only tools to help you build your tree. Once you discover a death date, baptism date, and or marriage date get a copy of the original. It is very rewarding to do so and you will learn more details about your ancestors.

Also this book does not include every descendant of theirs since that is impossible, it only includes the ones that I have identified through documents, reliable published, and unpublished works.
