Yuba County, California
Yuba County was one of the original counties of California, formed in 1850 at the time of statehood. Parts of the county's territory were given to Placer County in 1851, to Nevada County in 1851 and to Sierra County in 1852.
The county was named after the Yuba River by Captain John Sutter for the Native American village Yubu, Yupu or Juba near the confluence of the Yuba and Feather rivers. General Mariano Vallejo stated that the river was named Uba by an exploring expedition in 1824 because of the quantities of wild grapes (uvas silvestres in Spanish) which they found growing on its banks.
