In 1767, as the son of a primitivo poblador, Gervacio Hinojosa was granted Mier 8 by the King of Spain. Gervacio Hinojosa was the son of Diego Hinojosa, who died prior to 1750 (it is unclear whether his father was a settler). His mother, Ana Josefa de la Garza remarried Francisco Guerra and they moved to Camargo by 1750. In 1767 there was an improved estancia at the site.
