The Tongva (pronounced /ˈtɒŋvə/ TONG-və) are a Native American people who inhabited the area in and around Los Angeles, California, before the arrival of Europeans. Tongva means "people of the earth" in the Tongva language, a language in the Uto-Aztecan family. The Tongva are also sometimes referred to as the Gabrieleño/Tongva (often written "Gabrieleno/Tongva") or Gabrielino/Tongva tribe. Following the Spanish custom of naming local tribes after nearby missions, they were called the Gabrieleño, Gabrielino, or San Gabrieleño in reference to Mission San Gabriel Arcangel.

I haven't read much of this yet, but I did peruse a few pages. Looks pretty interesting. I hope it gives me some insight about the people who lived in this area!
