PETAO INDIANS. The Petao Indians are known only from records of the La Salle expedition, which indicate that in the late seventeenth century these Indians lived well to the north or northeast of Matagorda Bay, possibly between the Brazos and Trinity rivers. The Petaos have been erroneously equated with the Petaro and Petzare Indians, whose names also occur on the same list of Indian groups. The affiliations of all three groups remain unknown.
