San Diego County has maintained vital records since the 1850s, though early record keeping was inconsistent. California did not require birth and death registration until 1915. Many events before that year were never officially recorded. The county has marriage licenses from 1850 when it became one of California's original twenty seven counties. These early marriage records are particularly valuable since they represent the only official documentation for many pioneer families.
Mail requests should go to County of San Diego, Assessor-Recorder-County Clerk, P.O. Box 121750, San Diego, CA 92112-1750. Include a completed application form specific to the record type, payment by check or money order, a copy of your ID, and a self-addressed stamped envelope. Allow two to three weeks for processing. Personal checks may add processing time. Do not send cash through the mail.
Online Vital Records Requests
San Diego County offers online ordering for vital records through their website. The system processes orders electronically during business hours. Payment by credit card is accepted. Additional processing fees apply to online orders beyond the base certificate costs. The online system works well when you know exact details of the record you need.
Genealogists should request informational copies rather than certified copies. Informational copies cost the same but do not require notarized sworn statements. They contain all the same information as certified copies but display a legend stating they cannot be used to establish identity. This limitation does not affect family history research. Only authorized persons defined in California Health and Safety Code Section 103526 need certified copies for legal uses.
Online orders typically take one to two weeks to process and mail. Email confirmation arrives when the county receives your order. A second email comes when certificates are mailed via U.S. Postal Service. Tracking information may be provided for some orders. The county cannot expedite vital records processing regardless of ordering method.
San Diego Genealogy Resources
The California State Genealogical Society maintains its headquarters in San Diego. Their library and research center offers extensive collections for family history research. The society holds books, microfilm, databases, and vertical files covering California and beyond. Members can access the facility and receive research assistance from volunteer genealogists.
The San Diego Public Library Central Library has a special genealogy collection with California materials. The library provides free access to Ancestry.com, Fold3, and Newspapers.com for cardholders using library computers. Staff can guide researchers through available resources. The library also holds city directories, local histories, and cemetery indexes for San Diego County communities.
The San Diego History Center maintains archives with photographs, maps, manuscript collections, and oral histories. These materials supplement official vital records with context about neighborhoods, businesses, and daily life. The archives include materials from the 1840s forward. Researchers should call ahead to schedule archive visits and request specific materials.
San Diego County Historical Background
San Diego County formed in 1850 as one of California's original counties at statehood. The area had been under Spanish and Mexican control before American annexation in 1848. Early residents included Kumeyaay Native Americans, Spanish mission communities, Mexican rancheros, and American settlers arriving after the Gold Rush. This diverse population created records in multiple languages and formats.
San Diego remained relatively small until the late 1800s. The arrival of the Santa Fe Railway in 1885 sparked a land boom. Military installations including Naval Base San Diego, Marine Corps bases, and Coast Guard stations brought major population growth in the twentieth century. Families connected to military service may have records at these installations in addition to county vital records. Contact base archives or the National Personnel Records Center for military service records.
The county's location on the Mexican border created unique migration patterns. Many families moved between San Diego and Baja California. Some vital events may have occurred in Mexico rather than California. Mexican civil registration records and church records sometimes fill gaps when U.S. records are missing. The FamilySearch catalog includes many Mexican record collections accessible online or through local Family History Centers.
San Diego County did not experience the same earthquake damage as northern California counties in 1906. Records preservation was better as a result. However, some early records were lost to fires, floods, and simple neglect before preservation efforts began in the twentieth century. Microfilming projects in the 1970s and 1980s saved many deteriorating documents.
Types of Genealogy Records Available
Birth certificates show child's name, date and place of birth, parents' full names, parents' birthplaces, parents' ages, father's occupation, and mother's maiden name. San Diego County birth records from after 1960 include additional medical information. Earlier certificates provide basic facts only. Some births were registered years after the event, creating delayed certificates based on affidavits rather than contemporary documentation. Delayed certificates may have less accurate information.
Death records list decedent's name, date and place of death, age, birthplace, parents' names, marital status, surviving spouse, occupation, and cause of death. San Diego County death certificates also show informant's name and relationship. Funeral home and cemetery are listed if applicable. Death records help establish family relationships and point toward other records like probate files and cemetery records.
Marriage licenses include both spouses' names, ages, birthplaces, residence, occupation, parents' names, and previous marriages. Witnesses sign the license. The county Clerk issues licenses valid for ninety days anywhere in California. Licenses are recorded in the county where issued regardless of ceremony location. Public marriages from 1850 forward are available. Confidential marriages performed after 1971 remain sealed except to the spouses or by court order.
Property records maintained by the County Recorder show land ownership, transfers, mortgages, and liens. Deeds name family members and often state relationships. Homestead declarations protected family property from creditors and list household members. Mining claims in eastern county areas document economic activities. All recorded documents are indexed and available for research. Cross reference property records with vital records to build complete family histories.
Cities in San Diego County
San Diego County includes numerous cities and communities. The city of San Diego is both county seat and largest city with over 1.4 million residents. Other major cities include Chula Vista, Oceanside, and Escondido. All vital records for events in these cities are kept by the San Diego County Clerk-Recorder regardless of which city the event occurred in.
Smaller communities like Coronado, Del Mar, Encinitas, La Mesa, and Vista each have local history organizations and libraries with genealogy resources. These local repositories hold city directories, newspapers, photographs, and specialized collections. While they do not maintain official vital records, they provide valuable context and supplementary information for family history research.
Adjacent counties are Orange County to the north, Riverside County to the northeast, and Imperial County to the east. Mexico lies directly south. Families often moved between San Diego and neighboring counties or across the border. Check records in adjacent jurisdictions if you cannot locate a San Diego County record for an ancestor who lived near county boundaries.
San Diego County Research Strategies
Begin with online indexes before ordering copies. FamilySearch has digitized many California vital record indexes. The California Birth Index 1905-1995 includes San Diego County records. Search these free databases to verify a record exists before paying fees. Indexes provide enough detail to complete order forms accurately.
Check multiple spellings for surnames. Early recorders wrote names as they heard them. Spanish surnames were sometimes anglicized. Martinez might appear as Martines or even Martin. Given names varied too. Jose might be Joseph in English records. Women's maiden names sometimes got recorded incorrectly. Try variations if initial searches fail.
Look beyond vital records to military resources. San Diego's large military presence means many families have service records. The National Archives facility in San Diego holds military records for some service members. Veterans' death certificates note military service, pointing toward pension files and service records. Fold3 and Ancestry.com have digitized many military record collections.
Use cemetery records to supplement death certificates. San Diego County has numerous historic cemeteries including Mount Hope Cemetery, Greenwood Memorial Park, and El Campo Santo. Cemetery offices and findagrave.com list burials. Gravestone inscriptions sometimes provide birth dates and family relationships not found elsewhere. Some cemeteries have sexton records with additional details about burials and family plots.
Consider the border when researching San Diego families. Many events occurred in Mexico. Mexican civil registration began in 1859. Church records extend much earlier. The FamilySearch catalog includes Mexican records from Baja California and other states. Some families registered vital events on both sides of the border, creating duplicate records with potentially different information.
Note: Request informational copies for genealogy work to avoid notarization requirements while receiving complete information for family history purposes.
