Seattle's mother Sholeetsa was hiDkhw'Duw'Absh (Duwamish) and his father Shweabe was chief of the Dkhw'Suqw'Absh (the Suquamish tribe). Seattle was born some time between 1780 and 1786 on or near Blake Island, Washington. One source cites his mother's name as Wood-sho-lit-sa. The Duwamish tradition is that Seattle was born at his mother's village of Stukw on the Black River, in what is now the city of Kent, Washington, and that Seattle grew up speaking both the Duwamish and Suquamish dialects of Lushootseed. Because Native descent among the Salish peoples was not solely patrilineal, Seattle inherited his position as chief of the Duwamish Tribe from his maternal uncle.
