The correct answer is:
The Denny Party
The Denny Party, a group of American pioneers, which settled at Alki Point on November 13, 1851 and were credited with founding Seattle, Washington. Even though George Vancouver was the first European to visit this area in 1792, the date of the founding of Seattle is more related with the arrival of the Denny Party scouts in September 25, 1851.
