The city of Walnut, CA

About Walnut


Walnut, California, like most of America, was originally inhabited by a Native American tribe, in this instance, one called the Tongva. They were considered the most prominent of the region’s Uto-Aztecan indigenous tribes and often controlled & dominated trade amidst neighboring factions. Their settlements were mostly along the coastline of Los Angeles County, northwest Orange County, and surrounding islands.

When the Spanish came to this area in 1771, they established the San Gabriel Mission. Native Americans were converted and helped the Spanish by providing labor.

The land was hearty, and many orchards provided for the Spanish crown until 1833, when California fell into Mexico’s control and gave the San Gabriel Mission land to individuals.

The city’s name arose from one such individual land grant issued by the Mexicans, which referred to this area’s ‘Nogales,’ Spanish for the black-walnut tree native to this specific terrain.\

Several notable people lived in what would become Walnut, including William Workman and John Rowland, partners in a liquor business who pivoted to ranching and were granted tens of thousands of acres (including the future Walnut) by the Mexican government in the 1840s.

This land housed cattle and fruit crops for several decades.
