Marysville is a city and the county chair of Yuba County, California, located in the Gold Country region of Northern California. As of the 2010 United States Census, the population was 12,072, reflecting a fall of 196 from the 12,268 counted in the 2000 Census. It is ration of the Yuba-Sutter area of Greater Sacramento.

Marysville is located on the ancestral house of the Maidu, who occupied the Place for 10,000 years prior to the beginning of Jedediah Smith and trappers from the Hudson Bay Company in 1828, who were the first non-natives to scrutinize the area. Spanish and Mexican explorers never reached that far afield north upon the Feather River. In 1842, John Sutter leased allocation of his Rancho New Helvetia estate to Theodore Cordua, a original of Mecklenburg in Germany, who raised livestock, and in 1843 built a house and trading name he called New Mecklenburg. The trading publicize and house was situated at what would later become the southern halt of ‘D’ Street, Marysville’s main street. In 1844, the Mexican doling out granted Cordua his own estate grant, Rancho Honcut.

In 1848, Charles Covillaud, a former employee of Cordua, discovered privileged circumstances in the gold fields and bought half of the Cordua ranch. In January 1849, Michael C. Nye and William Foster, brothers-in-law of Covillaud’s wife, Mary Murphy, a survivor of the Donner Party, bought the new half of the Cordua ranch. They far along sold their captivation to Covillaud. In October of the thesame year, Covillaud sold most of the ranch to Jose Ramirez, John Sampson, and Theodore Sicard. During the Gold Rush, the ranch became a stopping dwindling for the riverboats from Sacramento and San Francisco that brought prospectors to the digging grounds. Even today a sign on the roadside as one enters Marysville describes it as the “Gateway to The Gold Fields.”

In 1850, Covillaud, Ramirez, Sampson, and Sicard hired Augustus Le Plongeon, a French surveyor, to Make a goal for a town called Jubaville, later called Yubaville. Stephen J. Field, a newly relocated attorney, purchased 65 lots of estate and drew up proper goings-on for estate being sold. Then, after just three days in the mining camp, he in style the nomination to manage for alcalde, a Mexican official, which amass the duties of a mayor and justice of the peace, in a extra government that was visceral formed. On January 18, 1850, Field defeated his rival, who had been in town just six days, and a town council was elected. That night, the townsfolk decided to declare the new town Marysville after Charles Covillaud’s wife, Mary Murphy Covillaud, the former wife of William Johnson of Johnson’s Ranch, and one of the surviving members of the Donner Party. After Marysville was incorporated by the other California Legislature, the first mayor was elected in 1851. Field went on to become one of the longest sitting members of the United States Supreme Court.
