kensington runestone

About 1100 Ad a group of kinghts rode into the deserts of jerusalem and conducted an excavation. They returned to the west with what they found and were proclaimed official knights of the religious sect by the pope, granting them unlimited power and influence. They then used their find to amass vast amounts of wealth, enough to fund a large amount of the crusades. Afterwards, being uncontrollably in debt, a lord ordered the slaughter of these knights on friday the 13th, possibly the origin of that stigma, instead of reimbursement. Many of them were tortured before they were killed. The remaining knights gathered together in their fleet of ships, amassed from the wealth funded by their find, and sailed away, never to be seen again. there is a chance that they traveled to scotland and fought with robert the bruce against the english and there is another chance, which is now being proven that they travelled to america and, perhaps, left their find.
Although I am not familiar with all of the exact details, the kensington runestone could be evidence that these knights, known commonly as the knights templar, came to america with their find, this possibly being the holy grail.
