Rancho San Ysidro


Rancho San Ysidro was a Spanish land grant in present day Santa Clara County, California, given in 1809 by Governor José Joaquín de Arrillaga to Ygnacio Ortega. Today's city of Gilroy is on former Rancho Ysidro lands, as is nearby Old Gilroy.

History

Ygnacio Ortega was the son of José Francisco Ortega. Ygnacio became a soldier and married Gertrudis Arce. In the 1790 California census, he is listed as mayordomo at the Mission San Gabriel. After Ygnacio's death in 1833, with Alta California under Mexican rule, Governor José Figueroa divided Rancho Ysidro among his three children.

John Gilroy, born in Scotland as John Cameron, was one of the first English-speaking residents of Alta California, having arrived in Monterey, California in 1814. He took his mother's maiden name, and was later baptized as "Juan Bautista Gilroy". In 1821 he married Clara Ortega. With brothers-in-law Quintin Ortega and Julian Cantua, Gilroy made soap near San Felipe Lake, which he traded along with onions and flour from his gristmill to Thomas O Larkin of Monterey.
Captain John C. Frémont and his troops passed through Rancho San Ysidro on their way south in November 1846 during the Mexican American War. They appropriated most of Gilroy's horses. John Gilroy served as an auxiliary alcalde and later as justice of the peace. When the town was incorporated in 1868, citizens honored Gilroy by naming their town after him. His adobe house, said to have been built in 1825, was located in what is now called "Old Gilroy" or "San Ysidro", 2 miles east of Gilroy. In later years Gilroy lost his property, and he died almost penniless in 1869.
The railroad arrived in 1869, making the community the hub of South Santa Clara County. With the completion of the railroad and the demise of John Gilroy, the growth of the community of San Ysidro shifted two miles west. The new Town of Gilroy was officially incorporated in 1870, becoming the largest community in Santa Clara County with a brewery, flouring mill and a distillery.
