Jim.... I am way behind in my reading. When I came across this it reminded me of the efforts of the Missouri Department of Nature and Parks, trying to officialize the location of the battle of Island Mound. One of our attendee's was a descendent of a member of the 1st Kansas Colored, a Private Vann. Vann was, as you noted an African American, Creek Indian. Thank you for supporting and acknowledging these brave soldiers.
