California CountiesThe U.S. state of California is divided into fifty-eight counties. On January 4, 1850, the California constitutional committee recommended the formation of 18 counties. They were Benicia, Butte, Fremont, Los Angeles, Mariposa, Monterey, Mount Diablo, Oro, Redding, Sacramento, San Diego, San Francisco, San Joaquin, San Jose, San Luis Obispo, Santa Barbara, Sonoma, and Sutter. On April 22, the Counties of Branciforte, Calaveras, Coloma, Colusi, Marin, Mendocino, Napa, Trinity, and Yuba were added. Benicia was renamed Solano, Coloma to El Dorado, Fremont to Yola, Mt. Diablo to Contra Costa, San Jose to Santa Clara, Oro to Tuolumne, and Redding to Shasta. One of the first state legislative acts regarding Counties was to rename Branciforte County to Santa Cruz, Colusi to Colusa, and Yola to Yolo.
The last California county to have been established is Imperial County in 1907.

San Mateo County History, Geography, and Demographics
Etymology - Origin of County Name
The county bears the Spanish name for Saint Matthew. As a place
name, St. Matthew appears as early as 1776, and the arroyo, the point and the
settlement at the unofficial San Mateo Mission are all so designated on the
early maps. Until about 1850, the name appeared as San Matheo.
County QuickFacts: Census Bureau Quick Facts
San Mateo County (pronounced /ˌsæn məˈteɪoʊ/ "san muh-TAY-o") (Spanish for: St. Matthew County) is a county located in the San Francisco Bay Area of the U.S. state of California. It covers most of the San Francisco Peninsula just south of San Francisco, and north of Santa Clara County. San Francisco International Airport is located at the northern end of the county, and Silicon Valley begins at the southern end. San Mateo County was formed from parts of San Francisco County and Santa Cruz County in 1856. The county seat is Redwood City.
So satisfying had been the growth of the county that in the spring of 1856 the Hon. Horace Hawes
introduced in the State Senate a bill entitled: "An act to repeal the several charters of the City and
County of San Francisco, and to consolidate the government thereof." This became a law and received the
governor's approval on April 19, of the same year.
According to the U.S. Census Bureau, the county has a total area of 741 sq mi (1,919 km²). 449 sq mi
(1,163 km²) of it is land and 292 sq mi (756 km²) of it (39.40%) is water. A number of bayside
watercourses drain the eastern part of the county including San Bruno Creek and Colma Creek. Streams
draining the western county include Frenchmans Creek, Pilarcitos Creek, Naples Creek, Arroyo de en Medio,
and Denniston Creek.

The history of our nation was a prolonged struggle to define the relative roles and powers of our governments: federal, state, and local. And the names given the counties, our most locally based jurisdictions, reflects the "characteristic features of this country!"
