Rancho San Juan Bautista

Rancho San Juan Bautista was a 8,880-acre (35.9 km2) Mexican land grant in present-day Santa Clara County, California given in 1844 by Governor Manuel Micheltorena to José Agustín Narvaez.

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.

[6] Narvaez sold a portion of the rancho to Éthienne Bernard Edmond Thée, who came to California from Bordeaux.

LeFranc was killed in an accident in 1887, and control of the company passed to his children, Henry, Louise and Marie.

[9] Masson helped guide the winery through the difficult days of Prohibition, then swapped the property in 1930 for Rancho Orestimba y Las Garzas.
