The name Giluts'aaw means literally "people of the inside" (referring to their traditional village site behind a small island on a slough along the Skeena).
However, one Giluts'aaw house-group (extended matrilineal family), the House of Niskiimas (belonging to the Ganhada or Raven clan), has members who are today associated with the Kitsumkalum community.
In the late nineteenth century the chieftainship of the Giluts'aaw was held by Victoria Young, a key convert of Lax Kw'alaams's Methodist missionary Thomas Crosby.
However, despite marrying a holder of the Gispaxlo'ots chieftainship Ligeex, she bore no children and after her death in 1898 the name Niisłgümiik was bequeathed to a brother's son of a different clan whom she had adopted into the Gispwudwada.
In 1915 the anthropologist Marius Barbeau photographed what remained of a "Prince of the Grizzlies" totem pole belonging to the Giluts'aaw Gispwuwada House of Niisnawaa at Lax Kw'alaams.
