The Clan MacDuff is a Scottish clan that originated in the medieval period. It is known for its historical role as the hereditary keepers of the Stone of Scone, which was used in the coronation of Scottish kings. The clan's name is derived from the Gaelic "Mac Dhuibh," meaning "son of the dark one," and it is associated with the region of Fife. The clan's chief was traditionally the Earl of Fife, a title that played a significant role in Scottish history. The MacDuffs were prominent supporters of the Scottish monarchy and were involved in various conflicts, including the Wars of Scottish Independence. Today, the clan is recognized as a part of Scotland's rich cultural heritage.
