Solano County, California

Solano County was one of the original counties of California, created in 1850 at the time of statehood. At the request of General Mariano Guadalupe Vallejo, the county was named for Chief Solano of the Suisun people, a Native American tribe of the region and Vallejo's close ally. Chief Solano at one time led the tribes between the Petaluma River and the Sacramento River. The chief was also called Sem-Yeto, which signifies "brave or fierce hand". The chief was given the Spanish name Francisco Solano during baptism at the Catholic Mission, and is named after the Spanish Franciscan missionary Father Francisco Solano.
