 Many were baptized as Roman Catholics by the Franciscan missionaries at the missions.Mission Indians were from many regional Native American tribes; their members were often relocated together in new mixed groups and the Spanish named the Indian groups after the responsible mission.For instance, the Payomkowishum were renamed "Luiseños" after the Mission San Luis Rey and the Acjachemem were renamed the "Juaneños" after the Mission San Juan Capistrano.
