Who are your top four Williams?
Use whatever criteria you like to define your four. All forms of the name are acceptable (Bill, Billy, Will, Willy, Liam, etc.).
Real people, living or dead, only. Please limit your nominees to four or less.
I’ll put up a poll in a few days, then we’ll get this settled once and for all.
mmm
Reading the title I expecting you to be asking which characters played by Robin Williams would I nominate…
That said, the only one coming to mind is Robin Williams. 
Williams Pinball Company, Williams Formula One Team.
William Faulkner
William Shakespeare
Billy Joel
Bill Clinton
That was harder than I thought. The first two were easy for me. The others were tough. I like Billy Joel and Bill Clinton well enough, but maybe not so much as to carve them into a mountain.
William Faulkner
William Blake
Willie Mays
Willie Dixon
Well, instead of echo some others let me add some alternatives:
William Shatner
Prince William
William Wallace
That’s all I got.
William Shatner
William Shakespeare
Willie Mays
Billy Dee Williams
William of Ockham
