What is "ginadoiks"

The Ginadoiks (sometimes called Gitnadoiks) are one of the 14 tribes of the Tsimshian nation in British Columbia, Canada, and one of the nine of those tribes making up the "Nine Tribes" of the lower Skeena River resident at Lax Kw'alaams (a.k.a. Port Simpson), B.C. The name Ginadoiks means literally "people of the rapids". Their traditional territory is the watershed of the Gitnadoiks River, a tributary of the Skeena. Since 1834, they have been based at Lax Kw'alaams, when a Hudson's Bay Company fort was established there.
