Robert Fiennes-Clinton, 19th Earl of Lincoln

The heir presumptive is the present holder's younger brother the Hon. William Roy Howson (born 1980). He assumed by Government Licence in 1996 the surname of Howson in lieu of Fiennes-Clinton. The heir presumptive's heir apparent is his son Jordan Ryder Howson (born 2004).

The seat of the Dukes of Newcastle was Clumber House near Worksop, Nottinghamshire. However, the house was demolished in 1938. The surrounding estate was sold to the National Trust in 1946 and is now a country park featuring a noteworthy Walled Kitchen Garden open to the public.

He was succeeded by his eldest son, the seventh Duke, who died childless and was succeeded by his younger brother. In 1881 the eighth Duke assumed by Royal Licence the additional surname of Hope on inheriting the substantial Hope estates through his paternal grandmother. On his death the titles passed to his only son, the ninth Duke. He had two daughters but no sons and was succeeded by his third cousin, the tenth Duke. He was the great-grandson of Lord Charles Pelham-Clinton, second son of the fourth Duke. He died unmarried in December 1988, having held the titles for only a month. On his death the dukedom became extinct while he was succeeded in the earldom by his distant relative, the eighteenth Earl, a descendant in the tenth-generation of the Hon. Sir Henry Fynes-Clinton, third son of the second Earl. Lord Lincoln lived all his life in Australia, and reportedly learned of his succession from a British newspaper. He wrote a book: Memoirs of an Embryo Earl. As of 2017 the title is held by his grandson, the nineteenth Earl, whose father had died in 1999. He is a Fellow of the Zoological Society of London, and still lives in Australia.

The Duke's two elder sons, George Pelham-Clinton, Lord Clinton, and Henry Pelham-Clinton, Earl of Lincoln, both predeceased him. He was therefore succeeded by his third son, the third Duke. He was a Major-General in the Army. On his early death the titles passed to his son, the fourth Duke. He served as Lord Lieutenant of Nottinghamshire from 1809 to 1839. He was succeeded by his son, the fifth Duke. He was a prominent politician and held office as Chief Secretary for Ireland, as Secretary of State for the Colonies and as Secretary of State for War. His eldest son, the sixth Duke, briefly represented Newark in the House of Commons. The Duke married Henrietta Adele, the wealthy heiress and daughter of Henry Thomas Hope.

Several other members of the Clinton family have also gained distinction. Edward Clinton, Lord Clinton, son of the fourth Earl, was Member of Parliament for Callington. The Honourable George Clinton, youngest son of the sixth Earl, was a Naval Commander, politician and Colonial administrator. His son General Sir Henry Clinton was Commander-in-Chief of the British in North America from 1778 to 1782. His sons General Sir William Henry Clinton and Lieutenant-General Sir Henry Clinton were also successful military commanders. Lord Edward Pelham-Clinton GCVO, second son of the fifth Duke, was a soldier and courtier.

His eldest son, the eighth Earl, died as a child and was succeeded by his younger brother, the ninth Earl. He was Cofferer of the Household and Lord Lieutenant of Nottinghamshire and Cambridgeshire. He married his first cousin Catherine Pelham (died 1760), daughter and heiress of Henry Pelham. In 1756 his uncle the Duke of Newcastle upon Tyne was created Duke of Newcastle-under-Lyne, with remainder to his nephew Lord Lincoln, and on the Duke's death in 1768 Lincoln succeeded as second Duke of Newcastle-under-Lyne according to the special remainder. He assumed by Royal Licence the additional surname of Pelham the same year.

His great-grandson, the fifth Earl, died without surviving issue in 1692 when the earldom and barony separated. The barony fell into abeyance between his aunts (see the Baron Clinton for further history of this title). He was succeeded in the earldom by his second cousin once removed, the sixth Earl. He was the grandson of Sir Edward Clinton, second son of the second Earl. His son, the seventh Earl, served as Paymaster of the Forces, as Constable of the Tower and as Cofferer of the Household. Lord Lincoln married Lucy Sydney (died 1736), daughter of Robert Sydney, 2nd Earl of Leicester (see the Earl of Chichester for earlier history of the Pelham family).

This creation of the Earldom was made for the eighth time in 1572 for the naval commander Edward Clinton, 9th Baron Clinton (see the Baron Clinton for earlier history of the family). He served as Lord High Admiral under Edward VI, Mary I and Elizabeth I. He was succeeded by his son, the second Earl. He represented Launceston and Lancashire in the House of Commons. His son, the third Earl, sat as Member of Parliament for Great Grimsby and Lincolnshire. In 1610 he was summoned to the House of Lords through a writ of acceleration in his father's junior title of Baron Clinton.

Earl of Lincoln is a title that has been created eight times in the Peerage of England, most recently in 1534. The title was borne by the Dukes of Newcastle-under-Lyne from 1768 to 1988, until the dukedom became extinct.

The Earldom was created for the seventh time in 1525 for Henry Brandon. He was the second son of Charles Brandon, 1st Duke of Suffolk, by his wife Mary Tudor. He died at the age of eleven in 1534 when the title became extinct.
