In 1767, as a primitivo poblador, Juan Jose Cisneros (Jimenez de Cisneros) was granted Camargo 79 by the King of Spain.

As the widow of the original grantee, Maria Antonia Guajardo inherited Camargo 79 from Juan Jose Cisneros (Jimenez de Cisneros).

In 1790 Manuel Tadeo Chavez de Caballero purchased Camargo 79 from Maria Antonia Guajardo. The tract was sold in 1784 via extrajudicial deed and formalized in 1790. See Sáenz Ramírez, Protocolos de Camargo p. 178; Seabury and Escobar, Family Tree Book, p. 352.
