There is not much information on the family clans, except from the oral tradition. The elders recount that the territories were initially of the Tshishe Manitu and were «loaned» to the family clans who had the responsibility of overseeing their equilibrium. Each family therefore had the job and responsibility of overseeing for eternity the territory that they occupied, by ensuring the survival of the animal species with whom they co-habited.
The notion of family reveals a particular character for the Ilnuatsh. In the sense that the extended family constitutes a basic social unit. It takes the form of a «hunting group», mainly in winter where one may find one to five families grouped together; up to 75 people.
