Hello Jim, We know that 42 Mississippians were present at the 75th Gettysburg reunion in 1938. Unlike the 50th reunion the states had to pay for travel to Gettysburg, at least the northern states did. But the 75th reunion travel was paid by the Federal government.

However the 42 at Gettysburg would only be with the ANV. I listed all of the United Confederate Veterans Camps in Mississippi I could find in an above post.
