Family
Lady Anne Cavendish-Bentinck was born in Kensington, the daughter of Conservative politician William Cavendish-Bentinck, 7th Duke of Portland (1893–1977). Her mother was Ivy Gordon-Lennox, daughter of Lord Algernon Charles Gordon-Lennox, son of Charles Gordon-Lennox, 6th Duke of Richmond. Lord Algernon was a close friend of Queen Alexandra, who was Lady Anne's godmother.
Cavendish-Bentinck came from an aristocratic family rooted in the height of the Anglo-Dutch ascendancy, the Glorious Revolution. Hans Willem Bentinck came to Britain from Holland with William of Orange in 1670 and was created Earl of Portland in 1689. His son, Henry, 2nd Earl, was created Duke of Portland in 1716.
The family accumulated property nationwide, including land in Marylebone, later redeveloped as part of Westminster, leading to Bentinck Street, Cavendish Square, Great Portland Street, Portland Place, Harley Street, named after a line of the Earls of Oxford into which a Bentinck married, and Welbeck Street, named after their seat, Welbeck Abbey in Nottinghamshire.
