Ruled by one of the Celtic princes known as Mormaers, the district of old Levanax (what is mainly Dunbartonshire today) was an important part of Scotland. From it arose the powerful Earldom of Lennox which became part of the Royal House of Stewart. The ancient principality of Lennox, embraced much of Loch Lomond in medieval times.
The ancient Earldom of Lennox included Stirlingshire, Perthshire, large parts of Renfrewshire and the whole of Dunbartonshire. The Earls of Lennox became joined to the Royal House of Stewart.
In late 13th century, the Earls of Lennox were among the most powerful nobles in the realm. The 5th Earl, Malcolm supported the Bruce claim to the Crown of Scotland.
Lennox fell victim to James I's hatred of all those connected to Murdoch, Duke of Albany, following the murder of the King's brother. This resulted in the execution of both Albany and Lennox in 1425. The succession of title disputed, the lands were divided.
John, Lord Darnley (husband of Mary, Queen of Scots), the son of the 4th Earl of Lennox, assumed the title in 1488.
In the 19th Century, the Lennoxes of Woodhead, later of Lennox Castle near Strathblane, claimed the right to succeed to the Title and Honours of the ancient Earls of Lennox, and although their claim to the peerage was never established, they were recognised as Chief of the name.
The present Duke of Richmond, Gordon and Lennox, proprietor of the famous Goodwood Racecourse, is Charles Lennox, direct descendant.
