Brownlow Bertie, 5th Duke of AncasterPC (1 May 1729 – 8 February 1809), styled Lord Brownlow Bertie until 1779, was a British peer and politician who sat in the House of Commons from 1761 to 1779 when he succeeded to a peerage.
Ancaster married twice. His first wife, whom he married on 11 November 1762 at the house of General Durand in Cork Street, Burlington Gardens, London, was Harriot Pitt (1745–1763), the only daughter and heiress of George Morton Pitt.[4] After the death of his first wife on 23 April 1763, he remarried to Mary Anne Layard (1733–1804), a daughter of Maj Peter Layard of Sutton Friars, on 2 January 1769 in St James's.[5] His first marriage was childless, while with his second wife he had one daughter:[5]
Lady Mary Elizabeth Bertie (1771–1797), married to Thomas Charles Colyear, 4th Earl of Portmore (1772–1835) on 26 May 1793; her son Brownlow-Charles Colyear inherited much property from his ducal grandfather but died in 1819 before he could inherit his father's titles.[6]
The dukedom and the marquessate became extinct on his own death, while the earldom passed to his kinsman Albemarle Bertie.[7] The Duke of Ancaster's funeral took place on 17 February 1809 at St Mary's Church in Swinstead, Lincolnshire.
