She married Charles Spencer, then Earl of Sunderland on 23 May 1732,[2] becoming Countess of Sunderland. The Earl's grandmother, Sarah, Dowager Duchess of Marlborough, disapproved of the marriage because Elizabeth's grandfather, the 1st Baron Trevor, had been a political opponent.[3] The dowager commented that "she has very bad teeth, which I think is an objection alone in a wife, and they will be sure to grow worse with time." Elizabeth became a duchess in the following year when her husband inherited the dukedom.[4] Together, they had five children:[5]
The couple lived at a lodge in the "Little Park" at Windsor, by the permission of Sarah Churchill, but the dowager was unhappy with the alterations made by the new duke, and forced them to move out in 1737, replacing them with Charles's younger brother John and his new wife.[7]
