MARIN. County seat, San Rafael. Created February 18, 1850. The origin of its name is not clear. One version is the county was named for Chief Marin, of the Licatiut tribe of Indians who inhabited that section and waged fierce battle against the early Spanish military explorers. The other version is that the bay between San Pedro and San Quentin points was named Bahia de Nuestra Senora del Rosario la Marinera by Ayala in 1775, and it is quite possible that Marin is simply an abbreviation of this name.
