Dear Ms. Mazzetti,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located a series titled the Applications Relating to the Enrollment of California Indians, 1928 - 1932 in the Records of the Bureau of Indian Affairs, 1793 - 1999 (Record Group 75) that may include the information that you seek. For access to these records, please contact the National Archives at College Park - Textual Reference (RDT1) via email at email@example.com.
We also located 63 series in Record Group 75 that pertain to the Mission Agency which covered many tribes in Southern California during the 1930s. After reviewing the series, please contact the National Archives at Riverside (RW-RS) via email at firstname.lastname@example.org for additional information.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDT1 and RW-RS. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Best of luck with your research!
