The Name Solano

Solano County was referred to as Benicia County before 1850 and the name Solano was  named after California became the 31st State of the Union on September 9, 1850.                                        

It was named indirectly from the Spanish Franciscan missionary, Father Francisco Solano. "Solano" is a common surname in Spain, specially in Navarra, Zaragoza and La Rioja. Father Solano's name was given in baptism to a Chief of the Suisunes in 1843, a Native American tribe of the region. Before his baptism, the chief was called Sem-Yeto (Brave or Fierce Hand). At the request of General Mariano Vallejo, the county was named after Chief  Solano, who at one time ruled over most of the land and tribes between the Petaluma Creek and the Sacramento River.
