My great great grandfather José María Guerra, the grandson of Eugenio Gutierrez, was the first of the Guerra-Cañamar family to successfully settle the 8,856-acre Los Ojuelos tract in 1857. José María’s father Isidro and grandfather Eugenio had previously tried to settle the land, but had been deterred and discouraged by Indian raids, and they subsequently returned to Guerrero Viejo (Revilla). José María settled Los Ojuelos with his brothers Dionicio and Juan Nepumoceno. They raised sheep and cattle and used the springs there to irrigate crops that sustained the settlement. A town of about 400 eventually grew up around the ranch of stone houses.
