Stillaguamish Tribe

Stillaguamish Tribe The Stillaguamish Tribe of Indians is the federally recognized tribe of the Stillaguamish people. Tribal headquarters are located in Arlington, Washington.

The Stillaguamish Tribe is composed of descendants of the 1855 Stoluck-wa-mish River Tribe. In 1855 the population resided on the main branch of the river, as well as the north and south forks. The name Stillaguamish, under various spellings, has been used since around 1850 to refer to those Indians who lived along the Stillaguamish River and camped along its tributaries. They were a party to the treaty of Point Elliott of January 22, 1855 under the spelling Stoluck-wa-mish. No separate reservation was established for the Stoluck-wa-mish Indians. Some moved to the Tulalip Reservation, but the majority remained in the aboriginal area along the Stillaguamish River.
