Absolutely contact Dr. Charles Sullivan, Professor Emeritus, at Mississippi Gulf Coast Community College. He has more stuff in his head than most archives, not to mention his Beauvoir connection. I also would be willing to share what I have on the 7th Mississippi, the High Pressure Brigade, Camps of Instruction, Conscript camps, Cavalry units, and Militia units. I also have much on the slaves who served with the 7th Mississippi and acted as servants, teamsters, mail carriers, and supply links to the troops out side of Mississippi.
