Bob Bryant's Nugget of Truth reveals that he, Jim Reed, and Johnny Ringo worked for Juan Mendoza.

The real Bob Bryant supposedly died in 1878 in Salma Canyon (I think that's the name), but there were legends back then that the body was misidentified, and that Bob Bryant continued his career as an outlaw working for various outlaw gangs.

Obviously Techland decided to play with that idea.
