Cartwright friends is the supporting cast of Bonanza. They include Hop Sing, Sheriff Roy Coffee, Will Cartwright, Doc Martin, Jamie, Griff, Clem, Sam the bartender, Betty Endicott, Bob Miles, Dusty Rhoades & of course, the horses (Buck, Sport, Chubb & Cochise).
Griff King played by Tim Matheson.
Griff was only ever in the 14th season, but he had lots of potential as a character.
He is one of my favorite Cartwright Friends.
