Among them is also mentioned that of San Antonio Abad as a rancho with 300 cattle, 80 horses, 25 mules and some grain fields on it.
It would later in 1833, be bounded on the north by the Rancho Melijo or Rancho de La Punta of Santiago E. Arguello, that lay from the line of hills south of the Tijuana River valley on the coast north to San Diego Bay.
[4] Following the Mexican American War, during the 1853-1854, invasion of Baja California by the filibuster William Walker his retreating force marching north along the El Camino Real to California, resting in ruined missions and abandoned ranchos along the way, finally encamped at the Rancho San Antonio Abad that lay just south of the border on the coast along the highway.
[5] A map of the Rancho Melijo made by a county surveyor for its land commission case, indicates that the line of hills extending along the border south of the Tijuana River and down the coast into Mexico, were known as the San Antonio Hills, perhaps indicating the northern limit of the Abad rancho.
On January 2, 1856, Santiago Arguello signed a sworn statement about the legal validity of the Mexican title of the San Pascual Rancheria.
