What is "chakchiuma"

The Chakchiuma were a Native American tribe of the upper Yazoo River region of what is today the state of Mississippi. The identification of the Chakchiuma by the French of the late 17th century as "a Chicacha nation" indicates that they were related to the Chickasaw and of similar Muskogean stock, as does the etymology of their name. The Chakchiuma have also been claimed to be the ancestors of the Houma tribe, who have a red crawfish as their war totem, though their existence as distinct groups at least from first contact with Europeans is confirmed by French encounters.
