[1] In 1875, Juan purchased one of the last remaining Mexican land grants, Rancho Calleguas, from the Ruiz family; it was later willed to his wife.

He and Isabella raised seven children: Frank, Isabel, Minerva, Rosa, Carmen, Ave Marie, and Martina.

Camarillo focused mainly in developing crops and became a leading innovator, bringing in lima beans, plus barley, corn, alfalfa, walnuts, and citrus.

He died of pneumonia on December 10, 1958, and was interred in the family crypt beneath St. Mary Magdalen Church in Camarillo, alongside his parents, his wife, sisters and brother.

This breed dates back to 1921, when Camarillo purchased a nine-year-old horse named Sultan from the Miller and Lux cattle ranch at the California State Fair in Sacramento.

Once a year Camarillo rode one of his white Arabians in the Fiesta of Santa Barbara while dressed up in a colorful Spanish costume.

[7] Many people of note have ridden on Camarillo White Horses including Governor Ronald Reagan, President Warren G. Harding, and 1946 Nobel Peace Prize recipient John Mott, as well as movie stars Leo Carrillo and Steven Ford (son of President Gerald Ford).

[8] Camarillo had leadership roles on the Ventura County Fair Board and on the California State Fair Board, and in the Camarillo City Chamber of Commerce, Peoples Lumber Company, Los Rancheros Visitadores, and California Lima Bean Growers Association.

According to Carol Yung, some of the land that Camarillo owned was in the Mission Oaks and Leisure Village area of the city that now bears his name.

[citation needed] The 4.5-acre (18,000 m2) property, including the barn and stable adjacent to the ranch house, was given to the city of Camarillo in 1997.

[3] This renovation included upgrades, exterior lighting, and a ranch-style fence around the perimeter as well as a new roof and utilities.

The Camarillo Ranch's mission statement includes: "To preserve, restore, and maintain The Camarillo Ranch as a historic site in partnership with our public and private sectors, on a self-sustaining basis; to foster its place in the rich history of California; to transform it into a focal point of the community for education, enrichment, and enjoyment; and to exhibit our diverse history and culture".

[3]According to Michael Lavenant, a board member from 2001 to 2011, the Camarillo Ranch House is available for weddings, receptions, bar mitzvahs, filming and corporate events.

For example, on May 20, 2010, Republican gubernatorial nominee Meg Whitman came to the Camarillo Ranch House for a campaign event to discuss immigration and education.

[10] Additionally, the ranch each year hosts two major fund raisers for the house: the Candle Light Gala and the Octoberfest Car Show.

The daughters also claimed that their brothers had deceived their mother and that Juan Jr. had confessed his guilt to one of the sisters and paid her $8,500.
