There is a legend that tells of an old Caddo chief who lived near the Sabine River and had twin sons. When the sons grew to manhood and were ready to become leaders of their own tribes, the father sent one brother three days eastward toward the rising sun. The other brother was sent three days toward the setting sun.The twin who settled three days toward the setting sun was Nacogdoches. The other brother, Natchitoches, settled three days to the east in Louisiana.
