Dear Ms. England,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the Population Schedules for the 1920 Census, the Population Schedules for the 1930 Census, and the Population Schedules for the 1940 Census in the Records of the Bureau of the Census (Record Group 29) that may contain information about the Frank Whelan in California. The 1940 Census schedules are digitized and available using the Catalog. For access to the non-digitized schedules, please contact the National Archives at Washington, DC - Textual Reference (RDT1) via email at email@example.com.
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. We apologize for this inconvenience and appreciate your understanding and patience.
For information about the U.S. Census, see the Census Bureau technical documentation and questionnaires as well as NARA’s page on Census Records.
You may wish to search Ancestry.com or FamilySearch.org for the U.S. Census. There may be a fee for using Ancestry. Instead, please check for access at your local library as many library systems subscribe to these sites, making them free for their patrons.
We also suggest that you review NARA’s Resources for Genealogists, as well as the document Suggestions and Advice for Family History Researchers may be useful.
Please contact the California Department of Public Health for birth certificates and death records since July 1905. The CDPH can ONLY provide certified copies of certificates for public marriages that occurred in the years 1905 to 1999 and 2009-2020. California County Recorder Offices can sometimes process requests faster than the CDPH. Copies of the actual divorce decree can only be obtained from the Superior Court in the county where the divorce took place.
If they were married in Colorado, please contact the clerk and recorder of the county that issued the original marriage license/certificate for a copy of the document. For a copy of the original divorce decree, contact the county district court that issued the document. The Colorado Department of Public Health & Environment provides verification of marriages, civil unions, and divorces for the years 1900 to 1939 and 1975 to present, recorded with the Colorado Office of the State Registrar. Verifications only contain the names, date, and county of the event.
We hope this is helpful. Best of luck with your family research!
