From a New York Times obit by Clay Risen headlined “Rock Brynner, 76, Son of Hollywood Royalty Who Cut His Own Path, Dies”:

Rock Brynner, whose life as a road manager for the Band, bodyguard for Muhammad Ali, farmer, pilot, street performer, novelist and professor of constitutional history overshadowed what, for a lesser mortal, might be a more than sufficient laurel on which to rest — he was the son of the actor Yul Brynner — died on in Salisbury, Conn.
