Apalachee

Apalachee was a Muskogean language of Florida. It was closely related to Koasati and Alabama. Apalachee was found to belong to the same branch of the Muskogean family as Koasati, Alabama, and Hitchiti. Apalachee was originally spoken in western Florida, but is believed to have last been spoken in the nineteenth century by Apalachee people that had been removed to Louisiana.
