Many events before that year were never officially recorded.

San Luis Obispo County History

San Luis Obispo County formed in 1850 as one of the original twenty seven counties when California achieved statehood. The county took its name from Mission San Luis Obispo de Tolosa, founded by Spanish missionaries in 1772. The mission period left records including baptismal, marriage, and burial registers that predate American civil registration. These mission records are now held by the Catholic Diocese and provide genealogical information for families with roots in the Spanish and Mexican periods.

Early American settlers included ranchers who took over Mexican land grants. The Ranchos created their own records through land transactions, livestock brands, and employment documents. Chinese immigrants arrived to build railroads and work in agriculture. Swiss and Italian dairymen established farms in the coastal valleys. Portuguese fishermen settled in towns along the coast. Each group left distinctive records reflecting their economic activities and community institutions.

The county remained largely rural and agricultural through most of its history. Population grew slowly until the late twentieth century. This small size meant county officials often knew residents personally. Early recorders sometimes added helpful notes about family relationships or previous names. However, the rural nature also meant some events occurred far from government offices and were never officially recorded. Births at remote ranches might not be registered for months or years. Some were never registered at all.

San Luis Obispo County escaped major disasters that destroyed records in other California counties. The 1906 San Francisco earthquake was felt but caused no significant damage. County records survived largely intact. This makes San Luis Obispo County valuable for genealogy research because nineteenth century records exist in better condition than in many other California counties.

San Luis Obispo County birth records from after 1960 include more detailed medical information. Earlier certificates provide basic facts only. Some births were registered years after the event, creating delayed certificates that rely on family recollection rather than contemporary documentation.

Research Tips for San Luis Obispo County

Start by contacting the Clerk-Recorder office to verify they have the record you need. Staff can check indexes and confirm record existence before you order. This saves time and money compared to ordering blindly. The phone number is 805-781-5080. Small county offices often provide better customer service than large urban counties.

Check alternate spellings for surnames. Early recorders wrote names as they heard them. Spanish names were sometimes anglicized. The surname Rodriguez might appear as Rodrigues or even Rogers in English records. Given names also varied. Jose might be Joseph in some documents and Joe in others for the same person. Try all reasonable variations when searching indexes.

Look beyond vital records to build complete family histories. San Luis Obispo County has newspaper archives, church records, and cemetery inscriptions. The local historical society and library have city directories, county histories, and biographical sketches. These supplementary sources provide context and details not found in official vital records.

Consider mission records for families with Spanish or Mexican heritage. Mission San Luis Obispo kept detailed registers from 1772 onward. These sacramental records predate civil registration and may be the only documentation for early families. The mission records include both Native Americans and Spanish/Mexican settlers. FamilySearch has microfilm copies available through Family History Centers.

Check adjacent counties for missing records. San Luis Obispo County borders Monterey to the north, Kern to the east, Santa Barbara to the south, and the Pacific Ocean to the west. Families moved between counties for work and opportunity. If you cannot find a San Luis Obispo County record, check neighboring counties where your ancestors might have been during specific events. Coastal families sometimes had connections to maritime communities up and down the coast.
