 In the 19th century, the Catawba moved west and were consolidated with the Cherokee, despite keeping their own traditions alive long term.It is also important to note that many of the southernmost Eastern Siouan tribes had largely homogenized their culture with that of the Muskogean populations beyond the Santee River.There were even isolated communities north of the river who are believed to have acted as Siouans, but spoke Muskogean.
