Ye of little faith,
The final Jesuit in the Superstitions, was Father Carlos Rojas in 1766. Father Rojas was appointed visitador general in 1763. Said to be too ill to perform those duties for the first two years, In reality he was spending 1763 and 1764 supervising the storing of church treasures and the closing/hiding of all mines in the Superstitions. In 1765 he finally took up his duties as visitador general.
As usual, the king's plans were no secret to the Vatican. The king's codes and cyphers were the laughingstock of Europe.
Source: "THE CODE BOOK" by Simon Singh. It had become obvious that the Jesuits tenure in the New World was coming to an end.
While Father Rojas was in the Superstitions, he began work on the Stone Maps. When he returned to Arizpe, the maps went with him to be hidden in the church. Years later, they were taken from the church for safety and while in transit were stolen. They were taken to Texas where they ended up in the hands of "Pegleg" Tumlinson, father of Travis Tumlinson, who claimed he found them just outside of the Superstitions.
The Jesuit who "covered" for Father Rojas, while he closed down the mines in the Superstitions was Father Bartolome Saenz. He kept things running smoothly at Arizpe.
Much of this is easily found in historical documents,
except for the Jesuit mining in the Superstitions. Even with his connections, I doubt even Lamar could reach this level in the Vatican Archives.
In this business, it's not so much what you know, as who you know.
Merry Christmas,
Joe
On the other hand, it wouldn't hurt to look into the history. After all, it concerns Jesuit treasure, so there's no telling where the trail might lead. By their very nature, a good Jesuit treasure story must blend truth with fiction. The trick in finding the treasure is separating the two.
