Hebrides Scots linked to Irish invaders

A new DNA study may prove a 10th century historical source which states that the western islands of Scotland were invaded by the Irish in the early 6th century. The new evidence shows "a significant Irish genetics component in Scots' ancestry." The study may also prove that the invasions occurred earlier than the 6th century.

Dr Wilson of Edinburgh University said: "It was extremely exciting to see for the first time the ancient genetic connection between Scotland and Ireland - the signature of a movement of people from Ireland to Scotland, perhaps of the Scots or Gaels themselves." The origin of the Gaels -- who by conquering and integrating with Pictish northern tribes created the Kingdom of Alba -- has been debated by historians for centuries.
