[Verginius Rufus]

Old Norse and its modern descendants are Germanic, not Celtic, languages. Norwegians settled Iceland and the Faroes in the 9th century to escape the rule of King Harald Fairhair. See the saga of Harald Fairhair in Snorri Sturluson's Heimskringla, chapter 19.

In chapter 22 of the same saga, it says that King Harald became aware of vikings in the Shetlands, Orkneys, and Hebrides, and sent expeditions to clear them out or kill them. Some of these men evidently settled in Iceland, along with those who went directly from Norway. The Celtic inheritance in Iceland would be from women taken as wives or concubines in the Orkneys, Hebrides, etc.

"Viking" is not a term for Scandinavians generally, but for men who went about plundering and marauding.

The Germanic tribes WERE Celtic tribes.  Sorry, but this is pretty basic stuff of history.

>"Viking" is not a term for Scandinavians generally, but for men who went about plundering and marauding.

Not one historian in a thousand would identify the word "Viking" with other than Scandinavians in general, and Norse in particular.
