Tree Removal in Gilroy, CA.

Spanish explorers led by Juan Bautista de Anza first passed through the Santa Clara Valley area in 1776, and in 1797 Mission San Juan Bautista was established near the Pajaro River. In 1809, Ygnacio Ortega was granted the 13,066-acre (5,288 ha) Spanish land concession Rancho San Ysidro. The village of San Ysidro grew nearby, at the foot of Pacheco Pass which linked the El Camino Real and the Santa Clara Valley with the San Joaquin Valley. California’s main exports at this time were hides and tallow, of which thousands of barrels were produced and shipped to the rest of New Spain. Trade and diplomatic intercourse with foreigners was strictly forbidden by the royal government but was quietly carried on by Californians desperate for luxury goods.

During the War of 1812, the armed merchantman Isaac Todd was sent by the North West Company to seize Fort Astoria, an American trading post at the mouth of the Columbia River. The ship, with a Royal Navy escort, departed from Portsmouth, England, made its way around Cape Horn and proceeded up the Pacific coast of the Americas, stopping at Spanish ports for supplies along the way. In January 1814, having fallen behind its escort, the Isaac Todd arrived at Monterey, California, the Spanish colonial capital of Alta California. During the visit, ordinary seaman John Gilroy (a Scotsman who had changed his name from John Cameron when he went to sea to avoid recognition) either (depending on the historical source) jumped ship or was left ashore to recover from scurvy.

John Gilroy (1794-1869), also known as Juan Bautista Gilroy, spent the next few years moving around among the missions, pueblos and ranchos, plying his trade as a cooper (barrel maker). At first, by his own account in an 1856 letter to Thomas O. Larkin, Gilroy was one of only two English-speakers resident in Alta California. Eventually, he found his way to Rancho San Ysidro, converted to Roman Catholicism and became the first naturalized English-speaking settler in Alta California. In 1821, the same year Mexico won its independence from Spain, Gilroy married a daughter of his employer, ranchero Ygnacio Ortega. Upon Ygnacio’s death in 1833, the rancho was divided among his three children-including Gilroy’s wife Maria Clara. In 1867, under U.S. property law, the Rancho San Ysidro (Gilroy) was patented to John Gilroy.
