Prior to the California genocide, the Ohlone people were not consciously united as a singular socio-political entity.
In the early twentieth century anthropologists and linguists began to refer to the Ramaytush Ohlone as San Francisco Costanoans—the people who spoke a common dialect or language within the Costanoan branch of the Utian family.
[4] In 1925, Alfred Kroeber, then director of the Hearst Museum of Anthropology, declared the Ohlone extinct, which directly led to the tribe losing federal recognition and land rights.
[5] The term "Ramaytush" (Rammay-tuš) meaning "people from the west," is a Chochenyo word the Ohlone of the East Bay used to refer to their westward neighbors.
[6] The term was adopted by Richard L. Levy in 1976 to refer to this peninsular linguistic division of the Ohlone which are the Ramaytush.
