Prior to European-American settlement, the Woodinville area was inhabited by the native Sammamish people. Indigenous peoples had occupied the area for thousands of years.
They [Sammamish People] are indigenous to the Sammamish River Valley in central King County, Washington.
The Sammamish speak Lushootseed, a Coast Salish language which was historically spoken across most of Puget Sound, although its usage today is mostly reserved for cultural and ceremonial practices.
