The Narragansetts are the lost Vinland Vikings.

For the first time in the long history of Vinland studies, an irrefutable factor has been established... genetic evidence of a pre-Columbian contact upon the eastern shores of North America.

The factor we have identified as G-4 - tuberculosis subversion among Narragansetts. A heretofore presumed aboriginal Native American Algonquin tribe of the eastern seaboard of North America - requires further discussion. A deliberate pause in publication of these papers for further research and testing of preliminary responses finds the need to clarify the issue. For it is found that many read only so far as the presence or absence of tuberculosis as an immunization factor, whereas the strength of our argument lies a bit deeper, in subsidiary fields of genetics. The intent of this paper is to transmit the theme into 'lay' language in several formats that the intricacy may be better understood, For the first time in the long history of Vinland studies, an irrefutable factor has been established with its cardinal corollary requiring rebuttal by the skeptic rather than, as heretofore reserving burdens of proof upon the theorist The point, we feel, is made and the thesis clear: the people now verifiable genetically distinct from all other American Aborigines. Pursuing the discussion need not be inferred as an attempt to strengthen a weak argument but solely to clarify the issue and perhaps moderate inimical viewpoints of those hesitant for religious or other reasons, to accept or consider potency of genetics and evolution of species as sciences..

A couple of paragraphs from the body of the article.

The factor 17 skeletons of 56 excavated with full scholarly provenance were discovered to possess lesions on rib, hip and spine bones resulting from the disease tuberculosis. So far as is now known this intense concentration or even any individual cases occurs at no other place upon the North or South American continents. We have shown that it was absent in a large sampling of skeletal remains of a similar tribe of Florida and also has not been identified, per se, or at least notable remark is absent in mummified remains of ancient aborigines of the altiplano of Peru.

Competently secured evidence shows that individuals of this geographically limited and culturally isolated northeastern woodland Algonquin group therefore possessed a response at distinct variance with other aborigines of the Americas to the toxin mycobacterium tuberculosis when exposed to it at the earliest stage of contact with Europeans. This response of delaying or subverting pathologies at such wide variance to the usual American native appears to have been typical of an European Caucasian population and (apparently) entirely absent in American Mongolian populations of the early colonial era. Individuals with skeletal lesions and cemetery demographics of their burials are emphatically more typical of Europe than America. The trait of partial immunity or subversion of - or to - TB in this district under study is established from three sources; direct remark of colonial neighbors: reliable census figures recorded in the identical time of burials: and recent discoveries of evidence within a primary gravesite and two secondary gravesites.

Summary

The reader has been requested to accept this argument: that a not inconsiderable body of evidence confirmed by a scientific finding manifests that the previously assumed aborigine people of the southern New England district known as Narragansetts are proven to have possessed genetic and anthropological attributes conjoining them to European attributes at a pre-Columbian age. Evidence presented also shows the appearance of at least some of these attributes as chronologically coincidental with demarcated recordings of exploration and colonization enterprises of Greenlanders/lcelanders a thousand years ago. This writer holds that the argument appears sufficiently refined as to be offered as proof that this southern New England coastline is the lost land of Vinland and; that Leif Ericsons and Thorfinn Karlseffnis landing sites have been found at the site of the coastal estuary of Pettaquamscutt immediately adjoining Narragansett bay. Assurance for this theme is reinforced by discovery that this view had been speculated from earliest colonial times by educated and informed settlers. The body of evidence permits, for this writer at least, no other position. The contemplative scholar is invited to weigh the discussion and inscribe this belief. Debate is solicited and encouraged but we will now proceed to analysis of sea conditions and courses from Greenland and upon the coasts of Vinland as informed truth rather superior to prosaic speculation. We trust that it will become apparent thereby that these navigational indicators demonstrate high statistical correlation's persuasively supporting this premise.
