Park History

(this information is according to to the park booklet)

O'Neill Park is part of the old Rancho Trabuco. The name Trabuco came about during a spanish expedition in 1769. On July 23-rd of that year, Gaspar de Portola led an expedition into what is now Orange County. The expedition camped a few miles east of the San Juan Capistrano area. On July 24-th, while the Portola group camped, one of the soldiers lost his "trabuco", or musket. To mark this loss, the stream was named Trabuco. The name has been associated with the canyon and adjacent mesa since then.

Mexican Governor Alvarado granted two square leagues to Santiago Arguello in 1841. Arguello sold these lands to Juan Forester in 1843. Forester received an additional grant of three square leagues in 1846. F.L.S.Pioche purchased the Rancho from Foresterin about 1880. Through the years various county pioneers held the title. The Rancho Trabuco eventually became the property of James L. Flood and Richard O'Neill Sr. The two were owners of Forester's other rancho -- Santa Margarita y las Flores. With their purchase, the two ranchos became the O'Neill Ranch.

In 1948, the O'Neill family donated 278 acres of Trabuco Canyon to the County of Orange for use as a regional park. Throughout the years the family donated additional acreage. The Ramakrishna Monastery, wishing to preserve native habitat, also gave property to the park. The Rancho Mission Viejo Company dedicated 935 acres, known as the Arroyo Trabuco, in 1982 and 735 acres, known as Tijerias Canyon, in 1996.
