Charles Dundas, 1st Baron Amesbury

Charles was a younger son of Thomas Dundas of Fingask, MP for Orkney and Shetland (1768–1771) and a commissioner of police in Scotland (31 January 1771), who died on 10 April 1786. His mother was his father's second wife, Janet, daughter of Charles Maitland, 6th Earl of Lauderdale. He was educated at Edinburgh Academy and Trinity College, Cambridge.[2] He was called to the bar from the Middle Temple, but devoted himself to a political life.

His father's younger brother Lawrence became a successful banker and an MP for over 30 years. Charles's older brother Thomas was a British Army officer who became Governor of Guadeloupe.

Dundas first sat for the borough of Richmond in 1774, Orkney and Shetland from 1781 to 1784, Richmond again in 1784–1786, and finally for Berkshire, which he represented in ten successive parliaments (1794–1832). He was, finally, the second eldest member in the house. He was a liberal in politics. In 1802, on the resignation of Mitford (afterwards Lord Redesdale), the then speaker, he was nominated, by Sheridan, as his successor in opposition to Abbot. He, however, withdrew from the contest. Dundas was Counsellor of State for Scotland to the Prince of Wales, and colonel of the White Horse volunteer cavalry. He was raised to the peerage as Baron Amesbury, of Kintbury, Amesbury, and Barton Court in the County of Berkshire, and of Aston Hall in the County of Flint, on 11 May 1832.[3] Apart from his political career he was also the first chairman of the Kennet and Avon Canal Company and the Dundas Aqueduct was named after him.

Lord Amesbury was twice married. His first wife, Anne, daughter of Ralph Whitley of Aston Hall, Flintshire, by whom he had one daughter, Janet, wife of Sir James Whitley Deans Dundas, who brought him the considerable estate of Kintbury-Amesbury (otherwise Barton Court) in Berkshire as well as other property. His second wife, whom he married on 25 January 1822, was his cousin, Margaret, daughter of Charles Barclay and widow of (firstly) Charles Ogilvy and (secondly) Major Archibald Erskine. He died 7 July 1832 at his residence in Pimlico, whereupon the title became extinct. Lady Amesbury died 14 April 1841.
