Thank you! That has to be it. It matches. Although there were only two Morgans: the one murdered and the brother who killed the murderer. I've been searching for documentation and details of this event for months. How and where did you find that newspaper and excerpt? As I wrote in my original post, I didn't have first names for the Morgans, units or states of origin, so that was a big hindrance. And two sources where I found mentions spelled Provost Marshal Morgan's killer's name "Little." If it was, in fact, "Littell," that opens new avenues to find him.
