In 1961, a Pataxó speaker named Tšitši'a was recorded by Wilbur Pickering in Posto Caramurú (located 3 kilometers from Itaju, Bahia). Tšitši'a was married to a Baenã woman, but she could not speak the Baenã language. Pataxó people were also reported to be living in Itagüira, Itabuna, Bahia.^[2]

Pataxó as documented by Prince Maximilian of Wied-Neuwied during the early 1800s^[3] is distinct from Pataxó-Hãhãhãe. It was historically spoken from the Mucuri River to Porto Seguro in southern Bahia from at least the 17th century.^[4]

From at least the 19th century, the Pataxó-Hãhãhãe had historically occupied a region stretching from the Pardo River to the de Contas River in southern Bahia.^[4]
