Garage Door Opener Installation in Rancho Mission Viejo, CA

Prior to the founding of the ranch, the land was the site of Acjachemen village of Piwiva. The ranch was established in 1845 when John (Don Juan) Forster acquired Rancho La Paz and Mission San Juan Capistrano. Forster added these properties to Rancho Trabuco, which he had purchased in 1843. Forster’s brother-in-law was Pío Pico, governor of then-Mexican-held California. In 1864, Forster added Rancho Santa Margarita y Las Flores to his holdings, which then totaled about 200,000 acres (81,000 ha), making him one of the largest landowners in the state.

After Forster died in 1882, Irish immigrants Richard O’Neill Sr. and James Flood acquired the ranch, taking equal ownership of the Rancho Santa Margarita y las Flores, Rancho Mission Viejo and Rancho Trabuco lands. Flood provided the money to purchase the ranches; O’Neill, offering his skills as a cattleman as sweat equity, agreed to work out his half as resident manager. Under O’Neill, the cattle herd was expanded, the land was improved, row crops were introduced, and the ranch became Orange County’s largest producer of wheat.

In 1907, James L. Flood, son of the original owner, made good on his late father’s promise and conveyed an undivided half interest to O’Neill Sr. Four months later, declining health caused O’Neill to deed his interest to his son, Jerome. In 1923, the sons of Flood and O’Neill consolidated their partnership with the Santa Margarita Company. Shortly thereafter, both men died.
