Georgiana Charlotte Cholmondeley, Marchioness of Cholmondeley (; 7 August 1764 - 23 June 1838), formerly Lady Georgiana Charlotte Bertie, was the wife of George Cholmondeley, 1st Marquess of Cholmondeley.
She was the daughter of Peregrine Bertie, 3rd Duke of Ancaster and Kesteven, and his second wife Mary. She married the marquess, then still an earl, on 25 April 1791 in London. They had three children:[1]
The earl already had an illegitimate daughter, Harriet, born around 1790 to his mistress, Madame Saint-Albin. Also living in the household was Georgiana Seymour, an illegitimate daughter of an earlier mistress, Grace Dalrymple; Georgiana's father was probably the Prince of Wales.[3]
Through the marriage between the earl and Georgina Bertie, the ancient hereditary office of Lord Great Chamberlain (which had been held by her brother, Robert Bertie, 4th Duke of Ancaster and Kesteven, until his death in 1779) passed into the Cholmondeley family.[4] Georgina's son George Cholmondeley, 2nd Marquess of Cholmondeley, shared the position.[5]
In 1795, the marchioness (then still a countess) was appointed a Lady of the Bedchamber to the Princess of Wales.
Their family home was Cholmondeley Castle in Cheshire, which was rebuilt in 1801-04 according to the earl's own design. In 1815 he was created Marquess of Cholmondeley, making his wife a marchioness.
Lord Cholmondeley, who was fifteen years his wife's senior, died in 1827, and was succeeded by his eldest son George. The dowager marchioness died at Carlton House Terrace in London, aged 73.[6]
