That is true even though my family comes from Vik Norway doesn't mean all of them were Vikings....my husband's family actually does have his family traced back to Viking ancestery through his Norwegian side of the family... they can tell by last names and trades... but he has not done a dna test and doesn't plan to....and if he did it would only show scandinavia...the summary for the Beta test said this...
About Your Region
Looks like you may have some Viking blood in you. Your genetic ethnicity ties you to Scandinavia, which includes the modern-day nations of Norway, Sweden, and Denmark. While the Vikings were feared by the coastal towns of medieval Europe as seaborne raiders and violent pillagers, they were also well-travelled merchants and ambitious explorers. They raided the Mediterranean coast of Africa, settled areas as far south as the Black Sea, and traded with the Byzantine Empire. And it was a Norse sailor, Leif Ericson, who is credited with being the first European to travel to North America—500 years before Columbus.
