Lame Deer's son, Archie Lame Deer, was a ceremony seller in Germany. He's passed on, so there's not much point in a thread on him. Generally we avoid going after the deceased, it's just wrong to do. The major exception we have to make is when their followers continue to use their name and promote them as an alleged great leader or healer.
Archie did have kids who were raised in Germany. They'd be young adults by now, but I don't know what they do.
