I'm reading through Rasmus B. Anderson's America Not Discovered by Columbus, and there are clearly some things here which are outdated in their understanding, but some things which still seem to hold true. Somewhere near the middle Anderson suggests that the body of The Skeleton in Armor was actually that of Thorvald, and that where he had died was in that place in Massachusetts, and that chemical analysis found the armor to be reminiscent of that used by the Vikings. Having googled this I'm coming up short on contemporary analyses of the Skeleton or of Thorvald's place of death---is Anderson's take a possibility? I know Vinland generally centered around Newfoundland but did the Vikings get as far as New England?
As I summarized before in: Was there a Norse fort located in Provincetown, MA? is it really mentioned in the Sagas?, and also as you wonder in OP, the identification of Vinland with somewhere around New England is based on the outdated hypothesis of the 19th century.
Almost every serious academic has not located the main place where the main events of Vinland sagas allegedly occurred with New England anymore after the discovery of L'Anse aux Meadows in 1960s.
