Clan Lyon is a Scottish clan. History Origins of the clan Genealogist Sir Iain Moncreiffe stated that the Lyons were a family of Celtic origin and that they were descended from a younger son of the Clan Lamont. However it is more generally accepted that the Lyons descend from a French family called de Léon. At the end of the eleventh century the de Leons had come north with Edgar, son of Malcolm III of Scotland to fight against his uncle, Donald Bane. Edgar was victorious and the de Leons received lands that were later called Glen Lyon in Perthshire. In 1105 Roger de Leonne witnessed a charter from Edgar to Dunfermline Abbey. 14th, 15th and 16th centuries Robert II of Scotland granted to Sir John Lyon, who was known as the White Lyon due to his complexion, the thanage of Glamis and five years later he was made Chamberlain of Scotland.
