Juan Salvio Pacheco II (1793–1876) was the grandson of Juan Salvio Pacheco (1729–1777) and Maria Carmen del Valle, who came to California with the Anza Expedition in 1776. Salvio Pacheco II, son of Ygnacio Bernardino Pacheco, was born in San Jose and enlisted in the military, serving at the Presidio of Monterey and the Presidio of San Francisco. In 1827, Pacheco was serving as a senior civil servant at the Pueblo of San José. When Pacheo received the grant in 1834, his son, Fernando Pacheco, was sent to occupy the grant and begin cattle operations. Salvio Pacheco did not move the rest of his family to the rancho until 1846.
