Other skeletons were recovered from Orkney, Scotland, where despite having no genetic link, the bodies were buried in Viking fashion.
The discovery suggests the Orkney locals adopted the Viking way of life, further expanding the scope of the who the Vikings were.
According to the researchers, Vikings from what is modern-day Norway travelled to Scotland, Ireland, Iceland and Greenland.
Vikings from modern-day Denmark made their way to England and Vikings from what is today Sweden, found themselves in the Baltic states.
Dr Ashot Margaryan, first author and Assistant Professor at the University of Copenhagen, said: “We carried out the largest ever DNA analysis of Viking remains to explore how they fit into the genetic picture of Ancient Europeans before the Viking Age.
