Since WE HAVE ACTUAL PROOF that the Vikings were in North America and they were fair haired....most likely the folks mentioned in this article were likely to have been NORTHERN EUROPEANS or WELSHMEN. I have even read that St. Brendan, the Irish Saint, came to the NEW WORLD in the 5th or 6th century.
The Vikings were great explorers...even went to Constantinople in the 3rd or 4th centuries, I think.
I wonder. My husband, who is supposedly mostly German and some English, looks very Mediterranean. A Moroccan asked him recently if he was Arabic. When I mentioned my genealogical research to our family doctor, he mentioned that my husband looks a lot like some of his Welsh immigrant patients who are working here. I just thought that was very interesting.
