Two rivers anciently bore the name of "Chicasa river," not because they were partially or exclusively inhabited by tribes of this nationality, but because their headwaters lay within the Chicasa boundaries. This gives us a clue to the topographic position of the Chicasa settlements. Jefferys (I, 153), states that "Chicasa river is the Maubile or Mobile river, running north and south (now called Lower Alibama river), and that it takes its rise in the country of the Chicasaws in three streams." When L. d'Iberville traveled up the Yazoo river, the villages on its banks were referred to him as lying on "la rivière des Chicachas."[55]
