Lord Edward Bentinck

Bentinck was the second son of William Bentinck, 2nd Duke of Portland, by Lady Margaret Cavendish Harley, daughter of Edward Harley, 2nd Earl of Oxford. He was the only brother of Prime Minister William Cavendish-Bentinck, 3rd Duke of Portland.[1][2] He was educated at Westminster and Christ Church, Oxford, and went on a Grand Tour between 1764 and 1766.[2]

Bentinck sat as Member of Parliament for Lewes between 1766 and 1768,[2][3] for Carlisle between 1768 and 1774,[2][4] for Nottinghamshire between 1774 and 1796[2][5] and for Clitheroe between 1796 and 1802.[2][6] The Clitheroe seat was reportedly to be purchased by the Duke of Portland from the Lister family for £4,000. However, the money could not be found and Thomas Lister was granted a peerage on Portland's recommendation as compensation.[2] Despite his long parliamentary career Bentinck never held ministerial office.

Bentinck married Elizabeth, daughter of the dramatist Richard Cumberland, on 28 December 1782. They had two sons and two daughters:[7]

• Ven. William Harry Edward Bentinck (1784–1868), Archdeacon of Westminster
• Cavendish Charles Bentinck (1785–1809)
• Harriet Elizabeth Bentinck (died 1862), married 1809 Sir William Mordaunt Sturt Milner Bt
• Charlotte Georgina Sophia Bentinck (1789–1819), married 1814 Lt. Gen. Sir Robert Garrett KCB

He was said to have been rescued from financial difficulties by his elder brother, but spent the last years of his life in Brussels, apparently due to financial constraints.[2] He died in October 1819, aged 75. Lady Edward Bentinck died in 1837.[1]
