. . . Kensington stone which was found on a farm in Minnesota in 1898. It claims to be a marker of sorts from a Scandinavian team of explores. It would have functioned as a land claim, essentially claiming half of America as belonging to them. . . .
If this were true, and dispersed Israel (or part of it) had settled northern Europe, this would essentially mean that America was claimed as land belonging to an Israelite nation long before Columbus.
However, this runestone is generally considered to be a fake (although there is evidence to support it being authentic as well), and even if it was authentic, there is still a lot of extrapolating that goes into this theory.
I will admit up-front that all I know about the Kensington Stone is what I've read online, although I made sure to lookup websites both pro and con.
First of all, there is way to much extrapolating to get the theory you mentioned, IMHO. Here is all that the Stone says (translated two different ways from Old Norse):
Translation #1:
"8 Goths and 22 Norwegians on exploration journey from Vinland over the west. We camp by 2 skerries one day-journey from this stone. We were and fished one day. After we came home, 10 men red with blood and tortured. Hail Virgin Mary, save from evil. Have 10 men by the sea to look after our ship, 14 day-journeys from this island year 1362." Translation #2 (this one based on a fuller understanding of the runic alphabet):
8 Geats and 22 Norwegians on acquisition expedition from Vinland far west. We had traps by 2 shelters one day's travel to the north from this stone. We were fishing one day. After we came home, found 10 men red with blood and dead. AVM Deliver from evils. have 10 men at the inland sea to look after our ship 14 days travel from this wealth/property. Year 1362Here is the original:
