The Laxsgiik (variously spelled) is the name for the Eagle "clan" (phratry) in the language of the Tsimshian nation of British Columbia, Canada, and southeast Alaska.
Members of the Gitxon group can be found among the Nisga'a, among the Tsimshian tribes of Kitselas and Gitga'ata, among the Haisla nation at Kitamaat, and at Skidegate on the Queen Charlottes.
Barbeau's now discredited theories about the peopling of the Americas—he claimed a far more recent Siberian ancestry for the Tlingit, Haida, and Tsimshianic-speakers (Tsimshian, Gitksan, and Nisga'a) than is now known to be possible for any Amerindian group—included an assertion that the Gitxon people migrated from Siberia, via the Aleutian Islands and Kodiak Island in Alaska, "only a few centuries ago" (as he phrased it in the Preface to his Totem Poles).
(Barbeau also, controversially and by today's standards erroneously, attributed their adoption of the Eagle crest to the influence of Russian traders' heraldic emblems during the fur trade.)
This story tells of Gitxon's niece Dzilakons (variously spelled) and her engagement with a prince of the opposite moiety which led to a war between the two sides, spurring the Gitxon people's migration to the Nisga'a homeland on the Nass River, to the Tsimshian villages of Kitkatla and Kitsumkalum, and to the Cape Fox (in Nisga'a Laxsee'le) tribe of Tlingits in what is now Alaska.
In 1947, Edmund Patalas ("belonging to the Kitamat tribe at Hartley Bay") described to the Tsimshian ethnologist William Beynon the origins of the people of the "Gitxon" group who migrated from the land of the Queen Charlottes first to Kitamaat and then to the Gitga'ata people, where a branch of this group, the House of Sinaxeet, is now considered "the royal Eagle house of Kitkata."
