The Urbanization of the Sweetwater Valley: San Diego County by Eugene Victor Coleman

Our Mission

The Bonita Historical Society is dedicated to preserving, for public education and enjoyment, the culture, history, arts, crafts, and aesthetic facets of the region, specifically El Rancho de la Nación in South San Diego County.

The museum is located in Rancho de la Nación, which was a 26,632-acre (107.78 km2) Mexican land grant in southern San Diego County, California, given in 1845 by Governor Pío Pico to John (Don Juan) Forster. The grant encompassed present day National City, Chula Vista, Bonita, Sunnyside and the western Sweetwater Valley. Known as Rancho del Rey (Ranch of the King) under Spain, this land south of the Presidio of San Diego served since 1795 as a presidial cattle grazing ground. The ranch was renamed Rancho de la Nación (Ranch of the Nation) by Mexican authorities. In 1845, this six-square-league land grant was made by Governor Pico to his brother-in-law, John Forster. John Forster (1815–1882), born in England, came to California in 1833. In 1837, he married Ysidora Pico, sister of Pío and Andrés Pico. John Forster was later the owner of the Rancho Santa Margarita y Las Flores, and Rancho Valle de San Felipe.  The museum houses a collection of brands and maps of the Mexican Land Grant period of California history.
