Elizabeth Sackville, Duchess of Dorset (c. 1689 – 12 June 1768), formerly Elizabeth Colyear, was a British court official and noble, the wife of Lionel Sackville, 1st Duke of Dorset.
She was the daughter of Lieutenant-General Walter Colyear (who was a brother of the Earl of Portmore). In 1703, at the age of fourteen, Elizabeth came to court as a Maid of honour to Queen Anne, a position she inherited from her aunt Catherine Sedley, Countess of Dorchester.[1]
They were married in January 1709, but the marriage was not made public until the duchess became pregnant.[1] The couple had five children in all:
Between 1714 and 1737 She was a Lady of the Bedchamber[2] and to Caroline of Ansbach, wife of King George II of Great Britain. From 1723 to 1731 she was Caroline's Mistress of the Robes, a title that can be held by no one of lower rank than a duchess.[3] The arrangements for Caroline's appearance at her coronation in 1727 were, however, made by an experienced subordinate.[4]
