William Bartram, who traveled through these parts from 1773 to 1778, and published his "Travels" many years later,[11] calls them "Uche or Savannuca," which is the Creek Sawanógi, or "dwellers upon Savannah river." This name Savannuca, and many equally sounding names, have caused much confusion concerning a supposed immigration of the Sháwano or Shawnee Indians (of the Algonkin race) into Georgia, among historians not posted in Indian languages. Sawanógi is derived from Savannah river, which is named after the prairies extending on both sides, these being called in Spanish sabana. Sabana, and savane in the Canadian French, designate a grassy plain, level country, prairie, also in Span. pasture extending over a plain; from Latin sabana _napkin_. It still occurs in some local names of Canada and of Spanish America. But this term has nothing at all in common with the Algonkin word sháwano _south_, from which are derived the tribal names: Sháwano or Shawnee, once on Ohio and Cumberland rivers and their tributaries; Chowan in Southern Virginia; Siwoneys in Connecticut; Sawannoe in New Jersey (about 1616); Chaouanons, the southern division of the Illinois or Maskoutens.
