Cool! Though nothing surprising, tbh! Given the huge Norse influence in the Highlands - many towns were founded by the Vikings such as Dingwall and Wick. On the Orkney and Shetland Islands they still retain a Norse identiy, infact on Shetland they practice a festival knwon as Up Helly Aa (http://en.wikipedia.org/wiki/Up_Helly_Aa). We need to remember Orkney wasn't part of Scotland untill 1472, up untill then it still belonged to the Norweigen crown.

Then, if we look at the Western Isles, the heart of the Kingdom of the Isles and the Gall-Ghaidheil people, archiologists have found many, many Norse & Viking items - including the famous Lewis Chessmen (http://en.wikipedia.org/wiki/Lewis_Chessmen). Infact, Clans MacLoed and MacDonald were founded - or their cheifs decent from - Vikings.
Just going to check out that link now! ... Cool! First 'fully intact' in UK!
