Iroquois in ancient times, settling in the backcountry of the Southeast United States, including what is now Tennessee. In 2010, more than 45,000 enrolled Six Nations people lived in Canada, and about 80,000 in the United States. The most common name for the confederacy, Iroquois, is of somewhat obscure origin. The first time it appears in writing is in the account of Samuel de Champlain of his journey to Tadoussac in 1603, where it occurs as "Irocois". Other spellings appearing in the earliest sources include "Erocoise", "Hiroquois", "Hyroquoise", "Irecoies", "Iriquois", "Iroquaes", "Irroquois", and "Yroquois", as the French transliterated the term into
Iroquois River (Indiana-Illinois) Iroquois River (Indiana-Illinois) The Iroquois River is a tributary of the Kankakee River in northwestern Indiana and northeastern Illinois in the United States. It was named for the Iroquois people. Via the Kankakee and Illinois rivers, it is part of the watershed of the Mississippi River. The Iroquois River rises in Jasper County, Indiana, and flows generally west-southwestwardly through Newton County, Indiana, and Iroquois County, Illinois, where it turns northward and flows into Kankakee County, Illinois. It enters the Kankakee River from the south in Kankakee County, opposite the village of Aroma Park, about southwest of the city of Kankakee.
