I don't have any guesses as to where this name actually did come from, though. Perhaps it is a name from a different Native American language and was mislabeled at some point; perhaps it was the (invented) name of an Indian heroine in a popular novel or movie; or perhaps it is just a variant of the name Taya.) The word/name is supposed to have some long meaning, like power of the moon or she dances lightly through the forest.. Native American words tend to be longer, not shorter, than English words.
