Clan Buchanan
Clan Buchanan (Scottish Gaelic: Mac a'Chanonaich or Bochanan) is an Armigerous Scottish clan
whose origins are said to lie in the 1225 grant of lands on the eastern shore of Loch Lomond to clergyman Sir Absalon of Buchanan by the Earl of Lennox.
Traditionally, Clan Buchanan can trace its chiefly line back to Anselan O Kyan who was of the clan Ó Catháin, provincial king of north Ulster (and had his seat in Limavady, Co. Londonderry) who landed in Argyll in 1016. However, the traditional account is inconsistent with other accounts for the period in Ireland, and may be little more than an origin myth. For his services against the Danes he is traditionally said to have received the lands of Buchanan from king Malcolm II which lie to the east of Loch Lomond around the village of Killearn.
