The titles Duke of Richmond and Duke of Lennox were created in the peerages of England and Scotland respectively in 1675 for Charles Lennox. The Duke of Richmond and Lennox was created Duke of Gordon in 1876. Thus, the Duke holds three dukedoms, more than any other person in the realm.

The subsidiary titles are: Earl of March (created 1675), Earl of Darnley (1675), Earl of Kinrara (1876), Lord Methuen (1675) and Baron Settrington (1675). The titles Earl Darnley and Lord Methuen were created in the peerage of Scotland along with the Dukedom of Lennox. The titles Earl of March, Earl of Darnley and Baron Settrington were created in the peerage of England along with the Dukedom of Richmond. Finally, the title Earl of Kinrara was created in the peerage of the United Kingdom with the Dukedom of Gordon. The eldest son of the Duke uses the courtesy title of Earl of March, Darnley and Kinrara.

The title Duke of Lennox was previously created for Esme Stewart in 1581. The first Duke of Lennox's eldest son, Ludovic Stewart, was made Duke of Richmond in 1623. The dukedom of Richmond became extinct at Ludovic's death. It was created again for James Stewart, the fourth Duke of Lennox. The title of Duke of Richmond soon became extinct again. Meanwhile, the Dukedom of Lennox merged with the crown when Charles II inherited it. Charles II then bestowed both titles on Charles Lennox, one of his illegitimate sons.
