Clan Ogilvy, also known as Clan Ogilvie, is a Scottish family from Angus, Scotland. Gillebride, Earl of Angus, received a barony from King William the Lion in 1163 and bestowed the lands of Ogilvy upon his son Gilbert. In 1429, Sir Patrick Ogilvy, who was later styled as Viscomte d'Angus, commanded the Scottish forces that fought alongside Saint Joan of Arc against the English, and Saint Joan of Arc marched into Orléans to the sound of bagpipes, accompanied by a guard of around 60 Scottish men-at-arms, and 70 archers. In 1491, King James IV elevated Sir James Ogilvy as Lord Ogilvy of Airlie. In 1615, Saint John Ogilvie was made a Scottish Jesuit martyr, as he was hanged for his faith, and he was canonised in the Roman Catholic Church. In 1639, the 7th Lord Ogilvy of Airlie was made the 1st Earl of Airlie by King Charles I for his support of the Crown in the Wars of the Three Kingdoms. The present Chief of Clan Ogilvie is David Ogilvy, 14th Earl of Airlie, and his uncle Angus Ogilvy married Queen Elizabeth II's first cousin, Princess Alexandra of Kent.
The historic seat of the earls of Airlie is at Airlie Castle. The Ogilvie Earls of Seafield branch were created in 1701 for James Ogilvy, 4th Earl of Findlater, who was the 1st Earl of Seafield, and the earldoms of Findlater and Seafield continued to be united until 1811, when the earldom of Findlater became dormant, while the earldom of Seafield remains extant, with its historic seat at Cullen House.
