Posse (Mario Van Peebles, not Kirk Douglas)

There seems to be more than a few uncredited–or, at the least, undercredited–actors in Mario Van Peebles' Posse. Does anyone know the actor who played, what I would call, the most significant member of Colonel Graham's Iron Brigade: the long-haired, blond knife wielder? A number of the actors are missing photos in IMDb but none of them seem to fit the character. I'm a pretty good researcher, normally, and Google hasn't provided any answers, either. 

Also, same question regarding the actor who plays the clergyman in the 10th with the Posse in Cuba.

Thanks.
