Notes…Born Lady Georgiana Charlotte Bertie to General Peregrine Bertie, 3rd Duke of Ancaster and Kesteven PC (1714-1778) and his second wife Mary. Georgiana was the eldest of three siblings.

Georgiana married the British peer and politician, George James Cholmondeley, 1st Earl of Cholmondeley, KG, GCH, PC (1749–1827) in 1791. Their family home was Cholmondeley Castle in Cheshire. In 1795, Georgiana Cholmondeley was appointed Lady of the Bedchamber to the Princess of Wales when still a Countess. George was created Earl of Rocksavage (County of Chester) and Marquess of Cholmondeley in 1815. Together they had two sons and one daughter: George Horatio Cholmondeley, later 2nd Marquess of Cholmondeley, William Henry Hugh Cholmondeley, later 3rd Marquess of Cholmondeley, and Lady Charlotte Georgiana Cholmondley. Their father, when an 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.

Lord Cholmondeley, who was fifteen years Georgiana’s senior, died in 1827, and was succeeded by the couple’s eldest son George. Georgiana died as the Dowager Marchioness of Cholmondeley at Carlton House Terrace in London, aged 73.
