Ygnacio Pacheco (1808 - 1864) was the grandson of Juan Salvio Pacheco (1729 - 1777) and Maria Carmen del Valle, who came to California in 1776 with the
Anza Expedition. Ygnacio Pacheco was born in
San Jose, the only child of Ygnacio Bernardino Pacheco, the alcalde of San Jose and cousin of
Salvio Pacheco, founder of
Concord. Ygnacio Pacheco was a soldier at the
Presidio of San Francisco. He retired in 1838 and was granted one and a half leagues in 1840. In 1846 he was alcalde of
San Rafael. With the
cession of California to the United States following the
Mexican-American War, the 1848
Treaty of Guadalupe Hidalgo provided that the land grants would be honored. As required by the Land Act of 1851, a claim for Rancho San Jose was filed with the
Public Land Commission in 1852, and the grant was
patented to Ygnacio Pacheco in 1861. Ygnacio Pacheco was married three times (Josefa Higuera, Guadalupe Duarte and Maria Loreto Duarte). When Pacheco died in 1864, he left the rancho to his five sons and one daughter. Maria Loreto Duarte, Ygnacio Pacheco’s widow married James Black, grantee of
Rancho Cañada de Jonive and owner of
Rancho Cañada de Herrera. ==See also==
