Lassen County, California Records

Lassen County was established on April 1, 1864 from Shasta County and Plumas County. Lassen County's name was derived from Mount Lassen, which was named in honor of Peter Lassen.  He was a Danish immigrant who settled in Plumas County before coming to the Honey Lake Valley around 1855.  He had a small mill in the area, but mainly looked for gold.  He was killed in 1859 out in the Black Rock Desert.  It has never been determined who killed him.  He also had a ranch down toward Lassen Peak before coming here.

Courthouse History - The first settlers of what was then known as Honey Lake Valley presumed that they were part of the Nevada Territory, though officials of Plumas County insisted that the valley belonged to California. After tensions on jurisdiction and taxation culminated in a shootout in February 1863, a survey of state boundaries determined that the valley was indeed part of California, and Lassen County was established. The Masonic Lodge and the Magnolia Saloon served as courthouses until a two-story wooden building was constructed in 1867. In 1915, residents approved a bond measure for a new courthouse built of native stone. It remains in use and is listed on the National Register of Historic Places.

The Clerk's Office DOES NOT DO RESEARCH. Most staff will assist people in finding the materials, but it is up to the individual to do the research. Some early court records from the various courts may have been sent to the California State Archives. Besides court minutes and judgements, these records include tax lists, wills, deeds, estate inventories, and marriage bonds. The California State Archives has microfilm of selected county records, 1850–1919.
