Lassen County was established on April 1, 1864 from Shasta County and Plumas County. The counties 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.

Lassen County Courthouse and Government Records
Researchers often overlook the advantages of Lassen County court, probate, and land files as a useful resource of genealogical details. Hidden away in California courthouses and archives everywhere tend to be the dreams and frustrations of the many California inhabitants.
The possibilities are great that your potential forefathers have left a detailed document of at least a number of facets of their lives in the Lassen County court records. Even if your ancestors is not mentioned in a Court case, contemplate all of the other methods that could have lead to her or him showing up in court records.
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.
Remember to get in touch with the clerk's dept to verify hours, mailing address, fees and other specifics prior to visiting or seeking information because of in some cases changing contact details. The Department Offices DO NOT DO RESEARCH. The data files are readily available to interested parties, barring private issues. A good number of employees will assist persons in obtaining the materials, but it's up to the person to do the research.
