Cybersecurity in Downey, CA

Mission San Gabriel Arcángel was initially founded on September 8, 1771, near settlements of the Tongva people. It was located in the Whittier Narrows on a bluff overlooking the Rio Hondo, near the intersection of today’s San Gabriel Blvd and Lincoln Avenue. After five years, flooding forced the relocation of the mission to its present site in San Gabriel.

In 1784, Governor Pedro Fages granted to former soldier Manuel Nieto (1734-1804) the largest of the land concessions made in what was then Alta California, a province of New Spain. Its 300,000 acres (120,000 ha; 1,200 km²) stretched from the Santa Ana River on the east to the Old San Gabriel River (now the Rio Hondo and Los Angeles River) on the west, and from the mission highway (approximately Whittier Boulevard) on the north to the ocean on the south. Its acreage was slightly reduced later at the insistence of Mission San Gabriel on whose lands it infringed. The Spanish concessions, of which 25 were made in California, were unlike the later Mexican land grants in that title was not transferred, but were similar to grazing permits, with the title remaining with the Spanish crown.

The Rancho Los Nietos passed to Manuel Nieto’s four children upon his death and remained intact until, in 1833, his heirs petitioned Mexican Governor José Figueroa to partition the property. The northwestern portion of the original rancho, comprising the Downey-Norwalk area, was granted as Rancho Santa Gertrudes to Josefa Cota, the widow of Manuel’s son, Antonio Nieto. At approximately 21,000 acres (8,500 ha; 85 km²), Santa Gertrudes was itself a sizable rancho and contained the old Nietos homestead, which was a center of social life east of the pueblo of Los Angeles. After the Mexican-American War concluded in 1848, many of the Californio ranchos were obtained by affluent Anglo-Americans who were immigrating west under the United States manifest destiny doctrine, and marrying into established Californio Spanish families. This migration was distinct from that prompted by the California Gold Rush farther north.
