There is ONE connection between George and the state:

Apples.

WA is known for it’s apples, but they were introduced to the area by the wife of Ft. Vancouver’s commander (iirc it was COL Barnes before he was sent back east). She lamented that the soldiers didn’t have enough fruit to eat, and sent letters to her friends asking for seeds. Among them were apple seeds from George Washington’s orchard- but by that point The Oregon Country had already been split into the Oregon and Washington territories.
