Inscribed stones of Oak Island

There has been much attention given to the stone markers of Oak Island. Ever since the original legend mentioned the existence of an inscribed stone discovered by the three boys in 1795, it seemed logical to look for similar markers which might yield clues as to the builders of the Money Pit and the location of the famous treasure. Do any of these inscriptions lead to the treasure?

What is the significance of these stones? Were they created by the originators or the Money Pit as markers, or could they be graffiti created by idle workers on their lunch break?

Could they even share a similar history to the famed stone at Gaspereau River, once thought to be inscribed by Captain Kidd himself?
