Sonoma County, located on the northern coast of California, an original county, created February 18, 1850. County seat, Santa Rosa. Sonoma is a Chocuyen Indian name translated by some as "Valley of the Moon" and by others as "land or tribe of the Chief Nose."
In the early 1850s the town of Sonoma had waned in importance in terms of both commerce and population, its county buildings were crumbling, and it was quite remote. As a result, components in the newer, rapidly growing towns of Petaluma, Santa Rosa, and Healdsburg began competing to move the county seat to their towns. The dispute was between the bigger, richer commercial town of Petaluma and the more centrally located, growing agricultural center of Santa Rosa. The fate was decided following an election for the state legislature in which James Bennett of Santa Rosa defeated Joseph Hooker of Sonoma. He then introduced a bill that ultimately resulted in Santa Rosa being confirmed as county seat in 1854. Supposedly, several Santa Rosans, not wanting to wait, decided to take action. One night they rode down the Sonoma Valley to Sonoma, took the county seals and records, and brought them to Santa Rosa.
As reported by the Census Bureau, Sonoma County has a total area of 1,768 sq mi (4,580 km2). 1,576 sq mi (4,082 km2) is land, and 192 sq mi (498 km2) (10.88%) is water.
