Originally, King County was named after William R. King, who was elected as Vice President, but did not serve due to ill-health (tuberculosis). He also owned a plantation.
The original reasons for naming the new territory after William King were somewhat self-interested (as wikipedia reports, to curry favor), but it’s a little unsettling to alter the historical record in such a way.
All else aside, and continuing with this line of thought, I hereby propose a new King of King County: The King of Pop:
In a few decades we’ll realize the true depth of his contributions. He has touched millions of people through his music and throughout his life.

Addition: R.I.P. I really hope no one in King County takes my suggestion seriously now. Andrew Sullivan has found a Mike Kinsley article from 1984, discussing Jackson’s talent and the fantasy bubble he inhabited that many, through their greed, supported.
