Who rode with Quantrill?

Cole Younger described his participation with Quantrill in a 1916 interview

There is no incident of the war which has been so distorted and misrepresented as the Lawrence Raid.  To understand what brought it about one has to dig into the history of the federal raids on the homes of southern sympathizers all over Missouri.  My father was opposed to the war and had friends on both sides, but he was shot down in cold blood and robbed by a gang of Federal free-booters as he was coming home from Kansas City.  … That day changed the course of my whole life, for, like Bill Anderson, whose sister was killed in the wreck of the federal prison in Kansas City, and whose mother and brother were shot to death in their home , the knowledge that my father had been killed in cold blood filled my heart for the lust for vengeance.  … I was nineteen on the day we started on the Lawrence raid.
