If the Rendón surname appears in your family tree, a new genealogy book may help you trace your ancestors across Nuevo León, Coahuila, Tamaulipas, and Texas.
Rendon, the 36th volume in the Last Names of Nuevo Leon book series, contains 540 pages of documented genealogical information. It follows eight generations of descendants connected to Diego Rendon and his wife, Maria de Valverde, beginning in the seventeenth century and continuing into the early 1900s.
Diego Rendon: Progenitor of the Rendón Surname
Diego Rendon is considered the progenitor of many Rendón families found throughout northeastern Mexico and Texas. His earliest known appearance in El Nuevo Reyno de Leon is in a record dated February 12, 1655, where he served as a witness.
In his will, dated October 5, 1678, Diego identified himself as the legitimate son of Bartolome Rendon and Catalina de la Fuente, who were residents of Mexico City. This suggests that Diego was probably born there before relocating to Nuevo León.
Diego worked as a merchant and lived in Monterrey. He died there on September 5, 1679. His wife, Maria de Valverde, was the daughter of Alonso Garcia and Leonor de Valverde. She died on March 7, 1676.
The Children They Raised as Their Own
One of the most fascinating parts of Diego and Maria’s story concerns the three children they raised: Juan, Ventura, and Maria.
In his will, Diego described them as children he had raised in his home and loved as his own. He named all three as his sole heirs.
Juan later married Maria Josepha Vega, while Ventura married Maria Lopez de Jaen. Maria married Pedro de Salas and, following that marriage, Nicolas Zambrano.
The biological parents of Juan and Ventura have not yet been identified. A marriage dispensation indicates that Maria’s biological father was Joseph Sanchez, although the identity of her mother remains unknown.
These unanswered questions provide present-day descendants with intriguing opportunities for additional documentary and DNA research.
More Than 5,500 Documented Descendants
During my research, I documented 5,596 descendants of the children raised by Diego Rendon and Maria de Valverde. Because of the enormous size of this family, the book focuses on the first eight generations that could be confirmed.
The genealogy is supported with citations intended to help researchers identify the sources behind the names, dates, marriages, and family connections. Readers should always obtain copies of the original records and independently verify information before adding it to their own family trees.
This book can serve as a valuable roadmap for finding those records and exploring Rendón family connections throughout the region.
