The most reluctantly accepted idea comes from John Jeffredo, an artist enrolled at Pechanga, who believes a seafaring people, whom  he calls the Island Shoshoni, once occupied the offshore islands that this map indicates were controlled by the Gabrieleño.

Dr. Eric Elliot believes he has linguistic evidence to show that the Luiseño were probably the original inhabitants of those islands.

Katherine Saubel believes that originally the eastern limit of Cahuilla territory was the Colorado River.

Carmen Lucas was taught that her people were a distinct group not called Tipai as the location of her ancestral territories would indicate when correlated with this map.  Many other people probably have ideas about original territories which contradict this map, too.
