Courtesy titles in the United Kingdom in the context of "Laird"

Frederick North, 2nd Earl of Guilford (13 April 1732 – 5 August 1792), better known by his courtesy title Lord North, which he used from 1752 to 1790, was Prime Minister of Great Britain from 1770 to 1782. He led the Kingdom of Great Britain through most of the American Revolutionary War. He also held a number of other cabinet posts, including Home Secretary and Chancellor of the Exchequer.

North's reputation among historians has varied wildly, reaching its lowest point in the late 19th century, when he was depicted as a creature of King George III and an incompetent who lost the American colonies. In the early 20th century a revised view emerged which emphasised his strengths in administering the Treasury, handling the House of Commons, and in defending the Church of England. The historian Herbert Butterfield, however, argued that his indolence was a barrier to efficient crisis management; he neglected his role in supervising the entire war effort.

Archibald Philip Primrose, 5th Earl of Rosebery, 1st Earl of Midlothian (7 May 1847 – 21 May 1929), was a British Liberal Party politician who served as Prime Minister of the United Kingdom from March 1894 to June 1895. Between the death of his father in 1851, and the death of his grandfather, the 4th Earl of Rosebery, in 1868, he was known by the courtesy title of Lord Dalmeny.

Rosebery first came to national attention in 1879 by sponsoring the successful Midlothian campaign of William Ewart Gladstone. His most successful performance in office came as chairman of the London County Council in 1889. He entered the Cabinet in 1885 and was twice Foreign Secretary, paying special attention to French and German affairs. He succeeded Gladstone as prime minister and leader of the Liberal Party in 1894; the Liberals lost the 1895 election. He resigned the party leadership in 1896 and never again held political office.

Duke of Somerset, from the county of Somerset, is a hereditary title that has been created five times in the Peerage of England. It is particularly associated with two families: the Beauforts, who held the title from the creation of 1448, and the Seymours, from the creation of 1547, in whose name the title is still held. The present dukedom is unique, in that the first holder of the title created it for himself in his capacity of Lord Protector of the Kingdom of England, using a power granted in the will of his brother in law King Henry VIII.

The only subsidiary title of the current duke of Somerset is Baron Seymour of Trowbridge, which is used as a courtesy title by the eldest son and heir of the duke. This courtesy title is the lowest in rank of all heirs to dukedoms in the peerages of the British Isles, yet the holder's precedence is higher than his title suggests, by virtue of the seniority of the Dukedom of Somerset (the only more senior non-royal duke is the Duke of Norfolk).

Earl of Arundel is a title of nobility in England, and one of the oldest extant in the English peerage. It is currently held by the Duke of Norfolk, and it is used (along with the earldom of Surrey) by his heir apparent as a courtesy title.
