Colusa County was first named Colusi County and occasionally called Coluse County. By 1855 the name was established as Colusa County. It is one of the original 27 counties created on February 18, 1850 but was administered by Butte County until 1851. The Colusa County location almost completely changed over the years. There remains in the present county only about a six mile wide strip from the original county. That strip is at the northern boundary of the present Colusa County (the southern part of the original Colusa County). In 1850 Colusa territory corresponded to what is now roughly Glenn County. Its southern boundary was several miles north of the City of Colusa. Territory which at one time was in Colusa County is now in Butte County, Glenn County, Lake County, and Tehama County. The present Colusa County has territory with six different Boundary Changes:
- A small portion of its present territory has been in Colusa County since 1850.

- Territory in Sutter County from 1850 to 1851, was in Butte County from 1851 when it was added to Colusa County.

- Most of present Colusa County was in Yolo County from 1850 to 1851 when the teritory was added to Colusa County.
The County was named after two Mexican land grants; Coluses (1844) and Colus (1845). The name of the county in the original state legislative act was spelled Colusi, and often in newspapers was spelled Coluse.

Colusa County Tax Office, 530-458-0450
The U.S. Internal Revenue Service Assessment List for California, 1862–66, is available on thirty-three microfilm rolls at the California State Library in Sacramento. The lists include names, location and description of business, and tax rate for individuals taxed.
Similar to tax records in their yearly listing of residents are the “Great Register” of California, which are miscellaneous county voting registers that exist from the mid-nineteenth century. The registers were compiled and printed about every two years. Before 1900, they show name, address, and age (but the age may remain the same after a man's first entry). From about the mid-1800s, physical descriptions are included, but after the 1898 register, only the name, address, party affiliation, and sometimes occupation are listed.
Before 1892, the lists are county-wide, but usually alphabetical only by first letter or surname. They are particularly valuable for foreign-born voters, as the date and court of naturalization are listed. Copies of the "Great Registers," (1866–1944) are at the California State Library, which also has alphabetical card file abstracts for some of the earlier registers for San Francisco. Records from 1946 are with the individual county registrars of voters.
