So, let me get this straight, as I am a straw brain.
Someone wrote a pamphlet, or shall we say story. Author not 100% known.
Said author, described a set of stories, even though both were 65 or so years prior.
Characters of said stories are not 100% known either. Could possibly be this person or that person, or neither.
This author somewhere along the line had to have been told or read about these stories, due to the time frame, prior to their writing of the pamphlet.
Said author was then getting stories at least second hand given to him. (We all know history is nothing more then what the teller wants us to know.)
Story is said to have treasure, of which it's make up is not 100% known.
Said treasure is hidden somewhere, again not 100% known.
So we have a maybe author, listing could be, maybe characters, about a possible treasure, hidden somewhere, about things that happened that he either read about or was told about? A story now at least second hand, so there is at least two chances of items being left out or missed by the second/third/forth telling? Whoops, forgot about 3 coded sheets, which the author could have been given, copied, or made up? And supposedly if your were to solve all the sheets, the treasure actually belongs divvied up to the folks listed on one of the sheets?
Dang, now I'm confused even more.
