Although most mtDNA lineages observed in contemporary Icelanders can be traced to neighboring populations in the British Isles and Scandinavia, one may have a more distant origin. This lineage belongs to haplogroup C1, one of a handful that was involved in the settlement of the Americas around 14,000 years ago. Contrary to an initial assumption that this lineage was a recent arrival, preliminary genealogical analyses revealed that the C1 lineage was present in the Icelandic mtDNA pool at least 300 years ago. This raised the intriguing possibility that the Icelandic C1 lineage could be traced to Viking voyages to the Americas that commenced in the 10th century...Original publication in the American Journal of Physical Anthropology in 2010, via Discover Magazine.
If the Greenland and ancient European hypotheses are rejected, what we have is a woman who entered the Icelandic society from an extinct lineage of Native Americans, probably from the northeast (or perhaps her Greenland Norse mother was of this line). What the Norse would have termed Markland. It is tempting to point to the Norse settlement at L’Anse aux Meadows in Newfoundland. Perhaps the Europeans had enslaved a native woman, and taken her back to their homeland when they decamped? But more likely to me is the probability that the Norse brought back more than lumber from Markland, since their voyages spanned centuries.
Finally, does this explain Björk? I doubt it...

Native American genes found in Icelanders
This is significant because it would indicate not just transatlantic contact with North America, but migration or mating in the preColumbian era.
