 You drive the streets of Mission Viejo every day, but do you know what’s behind their names? Much of Southeast Orange County was once part of the large cattle ranch that's still owned by the O'Neill/Avery/Moiso family. Since 1882, the family has been the steward of this land, managing cattle herds, growing all sorts of crops, and creating the communities of Mission Viejo, Rancho Santa Margarita, Las Flores, and Ladera Ranch. According to legend and local lore, as a tribute to family founders of the original land, and as a way of ensuring the ongoing legacy of the land that has been so good to them, the O’Neill/Avery/ Moiso family has named various streets found throughout Mission Viejo, Rancho Santa Margarita and now Ladera Ranch after key family members.
