Welcome to History Hub,
These websites offer a great deal of information about your inquiry.
Dear Ms. Vargas,
Thank you for posting your request on History Hub!
To begin your research, we suggest that you review the State of California’s Native American Heritage Commission website on California Indian History. Since the National Archives only has custody of records created by the federal government that document tribal nations administered by the Bureau of Indian Affairs, please reach out to NARA if you need to request records for a specific tribe or band.
We hope this is helpful. Best of luck with your research!
