The titles Earl of Mansfield in the County of Nottingham and Earl of Mansfield in the County of Middlesex were created in 1776 and 1792, respectively, for the Scottish lawyer and judge William Murray, 1st Baron Mansfield, fourth son of David Murray, 5th Viscount of Stormont. He was Lord Chief Justice of the King's Bench from 1756 to 1788. Murray had already been created Baron Mansfield, in the County of Nottingham, in the Peerage of Great Britain in 1756, with normal remainder to the heirs male of his body. The two earldoms were created with different remainders. The 1776 earldom was created with remainder to Louisa Murray, Viscountess Stormont, second wife of his nephew David Murray, 7th Viscount of Stormont, while the 1792 earldom, referring to a fictitious Mansfield in Middlesex to differentiate it from the first earldom, was created with remainder to his nephew the Viscount of Stormont. Lord Mansfield was childless and on his death in 1793, the barony became extinct. He was succeeded in the 1776 earldom according to the special remainder by his nephew's wife Louisa, the second Countess, and in the 1792 earldom according to the special remainder by his nephew Lord Stormont, who became the second Earl. The latter was a noted politician in his own right and served as Lord Justice General, Secretary of State for the Northern Department and Lord President of the Council. He was succeeded by his and the Countess of Mansfield's son, the third Earl. He was Lord Lieutenant of Clackmannanshire. On his death, the title passed to his son, the fourth Earl. He was a Tory politician and served as a Lord of the Treasury from 1834 to 1835 in the first administration of Sir Robert Peel. In 1843, he succeeded his grandmother the Countess of Mansfield and became in addition the third Earl of Mansfield of the 1776 creation. He was succeeded by his grandson, the fifth and fourth Earl. He was the eldest son of William David Murray, Viscount of Stormont. He died unmarried and was succeeded by his younger brother, the sixth and fifth Earl. His son, the seventh and sixth Earl, represented Perth in the House of Commons and served as Lord Lieutenant of Perthshire. The eighth and seventh Earl of Mansfield held office in the Conservative government of Margaret Thatcher as a Minister of State at the Scottish Office from 1979 to 1983, and at the Northern Ireland Office from 1983 to 1984. The titles are presently held by his elder son, the ninth Earl of Mansfield of the 1792 creation and the eighth Earl of Mansfield of the 1776 creation. He is also the fifteenth Viscount of Stormont, the fifteenth Lord Scone and the thirteenth Lord Balvaird. The family seat is Scone Palace, near Scone, Perthshire. The Earl of Mansfield is the Hereditary Keeper of Bruce's Castle of Lochmaben.
