Earl of Strathmore and Kinghorne

Earl of Strathmore and Kinghorne is a title in the Peerage of Scotland and the Peerage of the United Kingdom. The earl is also Chief of Clan Lyon.

History
The established history of Clan Lyon states that the family is of French origin, with the original name de Leonne, but James Balfour Paul, in his Scots Peerage, states that the family is likely of Celtic origin. The family's earliest recorded possessions, the thanages of Glamis, Glamis, Tannadyce and Belhelvies, were in a Celtic stronghold, while government positions held by family chiefs would have required fluency in Gaelic.

The first recorded family member, John Lyon, Lord of Glamis, was a courtier and diplomat, who was appointed Keeper of the Privy Seal in 1371 on the accession of Robert II. He acquired significant lands, and on 18 March 1372, Robert II granted him "the free barony of Glamuyss in the sheriffdom of Forfar." Glamis has remained the seat of the family ever since. His descendant Patrick Lyon, 1st Lord Glamis was created the first Lord Glamis in the Peerage of Scotland in 1445.

In 1606, the earldom was first created as Earl of Kinghorne in the Peerage of Scotland for Patrick Lyon, the ninth Lord Glamis, who was also created Lord Lyon and Glamis at the same time. In 1677, the designation of the earldom was changed to "Strathmore and Kinghorne" for Patrick Lyon, the third Earl. He was also granted the subsidiary titles of Viscount Lyon and Lord of Glamis, Tannadyce, Sidlaw and Strathdichtie. The 10th Earl sat in the House of Lords as a Scottish representative peer from 1796 to 1806, and again from 1807 to 1812. In 1815, he was created Baron Bowes in the Peerage of the United Kingdom, but upon his death five years later without legitimate issue, the peerage became extinct. The Scottish peerages were inherited by his younger brother, the 11th Earl.

The 11th Earl was succeeded by his grandson, the 12th Earl, who also sat in the House of Lords as a representative peer from 1852 to 1865. He married but left no children, and the peerages were inherited by his brother, the 13th Earl, who sat in the Lords as a representative peer from 1870 until 1892. In 1887, he was created Baron Bowes of Streatlam Castle, in the County of Durham, and of Lunedale, in the County of York, in the Peerage of the United Kingdom. This gave him and his successors an automatic seat in the House of Lords, which the earldom did not entitle them to until the Peerage Act 1963 extended that right to all holders of Scottish peerages. The 13th Earl was succeeded by his son, the 14th Earl, who in 1937 was created Earl of Strathmore and Kinghorne in the Peerage of the United Kingdom, leading to his becoming the 14th and 1st Earl of Strathmore and Kinghorne.

The eldest son of the earl uses Lord Glamis as a courtesy title. Normally, the highest subsidiary title (in this case Viscount Lyon) would be used, but Lord Glamis is used instead to prevent confusion with the officer of arms, Lord Lyon King of Arms. Queen Elizabeth The Queen Mother (1900–2002) was the daughter of the 14th Earl of Strathmore and Kinghorne, and the sister of the 15th Earl.

The family seat is Glamis Castle, in Angus, Scotland. Other family seats were Gibside, near Burnopfield, County Durham and Streatlam Castle, near Barnard Castle in County Durham. The traditional burial place of the Earls of Strathmore and Kinghorne is in an aisle of Glamis parish church.
