Clan MacDuff or
Clan Duff is a Lowland
Scottish clan. The clan does not currently have a chief and is therefore considered an
Armigerous clan, which is registered with the
Lyon Court. The early chiefs of Clan MacDuff were the original
Earls of Fife, although this title went to the Stewarts of Albany in the late fourteenth century. The title returned to the MacDuff chief when William Duff was made
Earl Fife in 1759. His descendant Alexander Duff was made
Duke of Fife in 1889.
