The County Clerk has divorce records from 1880 and probate and court records
from 1850. The County Recorder has birth, marriage, death and land records
18 February 1850: Los Angeles County was created as one of 27 original counties in the new state of California. Prior to the creation of the county, the records were either at city or Franciscan mission places.
The county was named for the City of Los Angeles. The County Seat is Los Angeles and was founded February 18, 1850. It is located in the southeastern area of the state.
The original County of Los Angeles covered a large part of Southern California including parts of what is now Kern County, San Bernardino County, Riverside County, and Orange County. These areas split off to form San Bernardino County in 1853, Kern County in 1866, and Orange County in 1889. In 1893 part of San Bernardino County that had originally been part of Los Angeles County became part of Riverside County.
For animated maps illustrating California county boundary changes, "Rotating Formation California County Boundary Maps" (1850-1925) may be viewed for free at the MapofUS.org website.
There is no known history of courthouse disasters in this county.
Los Angeles County contains 88 incorporated cities (2010) and many more named places. Los Angeles City also contains a large number of named areas many of which had their origins before they were annexed into Los Angeles.
Communities: Hacienda Heights, South Whittier, Topanga, Universal City, East Los Angeles, more...

California county clerks were to keep voting registers every other year from 1866 and well into the 20th century. These large books, called Great Registers, listed the men who registered to vote in that county. Besides name and age, the record may show place of birth, address, occupation, naturalization date and sometimes even a physical description.
