alan m: I'm not sure that the answers to your three questions - if the answers are even available - have any significance, other than the apparent fact that Waltz spent at least some time in Adamsville AZ. The first thing I would check is whether any complete biography is available for Charles S. Adams. I suspect that would be a complete dead end, but the importance here is not the flour miller, but the name "Adams" and the recognition it carries for the Organization loosely referred to as the KGC. Named things, people, places - those are the identifiers in treasure tales, especially those allegedly associated with the KGC.
As an aside, Jacob Waltz spent a couple years (late 1840s) in Natchez MS, in that the incubator for the founding of the KGC under Gen. Quitman. Natchez is the county seat of Adams County MS. [name recognition] Was Waltz indoctrinated there? Maybe, because he and other budding operatives (including, of all people, members of Jesse James' family) relocated to Paso Robles County CA, during the CA gold rush. Paso Robles became quite a western center of Southern political support prior to and during the Civil War.
As another aside: does anyone know the exact coordinates for the Tempe Mystery Glyphs shown below? If so, I'd like to know, because with that information I can provide you with an interesting map of the western Superstition Range that you can play around with concerning the LDM/PSM lore.

Oro: yes, the confusion, cross-pollination, disinformation, et al regarding these treasure tales is maddening. What else can you do except try to gather the earliest information available and try to reconcile it with later stuff? The problem then becomes in choosing which information is the most reliable.
rennes: to echo mdog, what is meant by your LUE comment?
Adams County, Mississippi is just north of Wilkinson County which was named after General James Wilkinson. Wilkinson built Fort Adams and was involved in a conspiracy to create a country on the west side of the Mississippi River. He was also a spy for the Spanish, as you already know. You have pointed out, many times, the Adams name as it relates to treasure legends and I think you might be onto something there. Even into modern times.
