Find much different spellings of language speakers and tribes/nations. Tupi may be the language family but people {tribes} would have there own Tupi language. This map helps place indigenous people and languages. In this map the Rio Tibirica area the spelling is Tupinamba. There also seems to to a Tupinamba speaking region to the north. The inland hills and possibly Rio Tibirica head waters may be Ge speakers. I am sure you all wanted to know this??
