The Macleans
The clan name Mac'Lean means 'Son of Gillean', and it takes this from the Thirteenth-Century warrior, Gillean of the Battle-Axe, who was related to the Kings of the Ancient Province of Dalrida.
The first recorded mention of the Macleans of Duart is in a papal dispensation of 1367 which allowed their Chief Lachlan Lubanach Maclean to marry the daughter of the Lord of the Isles, Mary Macdonald. This it is said, was a love match, and her father was persuaded to to allow it only after he had been kidnapped by Lachlan (an incident in which the Chief of the Mackinnons was killed). Thus the Macleans came to own much of Mull, the Mackinnon lands being granted to them by the Macdonalds as a dowry. Almost certainly, Lachlan built the keep that stands today though the great curtain walls were probably of the previous century.
The Macleans
The Clan
The Clan lands were, and are on the West Coast of Scotland and the islands of Mull, Coll, Tiree and Jura.
The Chieftains of the Clan Maclean had and still have lands on Morvern, Ardgour, Drimnin and at Dochgarroch on the mainland as well as on the islands. Those people living on these lands may, or may not have been related or they may have taken the name of Maclean for protection.
The spelling of Maclean is not important (McLean, MacClane, Maclain etc). There are other families who are also part of the Maclean family. The Rankins are a sept of the clan and traditionally provide a piper for the Chief.
Some of the names usually associated with the Macleans are Beath, Beaton, Black, Dewart, Macbeth, MacCormick, Macladyen, Macvey, Patten and Paton.
Members of the Clan are now spread throughout the world and many return to visit the homes of their ancestors and family.
This information comes from the Duart Castle website.
I will add to this information it is quite interesting. The MacLaines were a brutal bunch.
