In 1944, upon the death of her husband, Richard, and with the ranch lands held in trust, Marguerite “Daisy” O’Neill stepped forward to lead the family. With determination and pride, she kept the ranch land intact. To this day, Marguerite O’Neill’s admonition to “take care of the land and the land will take care of you” guides the family, and the community.
In 2005, the O’Neill family secured a science-based land use and open space preservation plan for the remaining 20,868 acres of family ranch. Under this plan, about 25% of The Ranch will be carefully planned over the next few decades into a new community, while the remaining 75% will be forever protected as The Reserve at Rancho Mission Viejo.
