Koroas afterward figure as one of the tribes settled on Yazoo river, formerly called also River of the Chicasa, and are mentioned there by D. Coxe, Carolana (1742), p. 10, as Kourouas. They were then the allies of the Chicasa, but afterward merged in the Cha'hta people, who call them Kólwa, Kúlua. Allen Wright, descended from a grandfather of this tribe, states that the term is neither Cha'hta nor Chicasa, and that the Koroa spoke a language differing entirely from Cha'hta.[38] A place Kolua is now in Coahoma county, probably far distant from the ancient home of this tribe. The origin of the name is unknown; the Cha'hta word: kánlo _strong, powerful_, presents some analogy in sound.
