About Mamenthoüensa, Chief of the Illini Confederation
Mamenthoüensa was Chief of the Kaskaskia ("Kaskaskahamwa") Tribe and rose to the position of Chief of the Illini Confederation. Today, he is most often referred to simply as Rouensa. Alternate names include Francois-Xavier Rouensa,, Mamentouensa, Mamantouensa, Mamenthousensa.
Many Louisianians with ties to Pointe Coupee and Avoyelles Parishes, can claim descendency from Rouensa, Chief of the Illiniwek Indian tribe in the late 17th/early 18th century, via his daughter,Marie.
The Illiniwek Indians (aka: Illini) were part of the Algonquin Indian nation that eventually relocated to the vicinity of Fort de Chartres.
