Georgiana Spencer, Countess Spencer

Margaret Georgiana Spencer, Countess Spencer, was an English philanthropist. She was born at St James's Palace as the daughter of a diplomat and a maid of honour to Caroline of Ansbach. In 1754, she married John Spencer, one of the wealthiest men of the era. A love match, the marriage resulted in the births of three surviving children, who included Georgiana Cavendish, Duchess of Devonshire. The Spencers became earl and countess in 1765, a reward granted by the Duke of Newcastle for John's political loyalty to the Whig party.
