California Genealogy Search at a Glance

California family history has two free statewide indexes that most states lack: the California Birth Index for 1905 to 1995 and the California Death Index for 1940 to 1997, both public and both searchable online. Before 1905, the county recorders kept births, deaths and marriages from the 1850s, and before 1850 the records are Spanish and Mexican mission and pueblo registers. The California State Archives in Sacramento holds the state's own records, and the 1852 state census fills the gap between the first federal census in 1850 and the Gold Rush boom.

California's 58 counties formed from 27 original counties in 1850, so early records for a family in Kern, Orange or Riverside sit in the parent county.

Vital records for California family history

California began statewide birth and death registration in 1905, and the California Department of Public Health holds the certificates, with county recorders holding copies and the earlier county registers from the 1850s. The statewide birth index for 1905 to 1995 and the death index for 1940 to 1997 are public and free online through several sites, and certified informational copies of any birth or death certificate are available to anyone. Marriage records are held by the county recorder or county clerk from each county's founding, with a statewide marriage index for 1949 to 1959 and 1960 to 1985, and divorce files sit with the superior court clerk.

California archives, census and military records

The State Archives holds the 1852 state census, the Great Register voter rolls kept by each county from 1866 to 1944, Spanish and Mexican land grant case files, state prison registers from San Quentin and Folsom, and the records of the Secretary of State and the state courts. The Bancroft Library at Berkeley and the Huntington Library in San Marino hold mission registers and rancho papers. Federal land patents are at the General Land Office site, and the National Archives at Riverside and San Francisco hold California's federal court, naturalization, Chinese Exclusion Act case files and immigration records from Angel Island and San Pedro.

County courthouse records in California

California county recorders hold deeds, mortgages and the pre-1905 birth, death and marriage registers, county clerks hold marriage licenses and naturalization records in most counties, and superior court clerks hold probate, divorce and civil case files. The 1906 San Francisco earthquake and fire destroyed the city's records, so San Francisco research relies on the Great Registers, city directories, church records and the reconstructed property records. Los Angeles County's recorder, the largest in the country, and most other recorders post grantor and grantee indexes online.

California Genealogy Search, questions

Is the California Death Index free?

Yes. The California Death Index for 1940 to 1997 and the Birth Index for 1905 to 1995 are public records available free through several genealogy sites, listing name, dates, county and mother's maiden name.

What are the California Great Registers?

Voter registration rolls kept by each county from 1866 to 1944, listing adult male citizens, and after 1911 women, with age, birthplace, occupation and address. The State Archives and FamilySearch hold them.

Where are San Francisco records from before 1906?

Most were destroyed in the 1906 earthquake and fire. Great Registers, city directories, church registers, newspapers and the reconstructed property records at the recorder's office are the substitutes.
