There is a gap in the archaeological record between the most recent Fort Ancient sites and the oldest sites of the historic Shawnee. The latter were recorded by European (French and English) archaeologists as occupying this area at the time of encounter. Scholars generally accept that similarities in material culture, art, mythology, and Shawnee oral history linking them to the Fort Ancient peoples, can be used to support the connection from Fort Ancient society and development as the historical Shawnee society. But there is also evidence and oral history linking Siouan-speaking nations to the Ohio Valley.
