Historically this name can be found in The Bible, as the name of the third son of King David, who was killed for rebellion against his father. First found in Argyllshire (Gaelic erra Ghaidheal), the region of western Scotland corresponding roughly with the ancient Kingdom of Dál Riata, in the Strathclyde region of Scotland, now part of the Council Area of Argyll and Bute, where they were seated from early times and their first records appeared on the early census rolls taken by the early Kings of Britain to determine the rate of taxation of their subjects.
