Note 216 — Chapter XXII · THE GATHERING STORM.
Reading edition
This lady, Charlotte Sophia, the young Countess Platen referred to once or twice in the correspondence, was said to be the daughter of Countess Platen by the Elector Ernest Augustus. She married, later, Baron Kielmansegge, Master of the Horse, and accompanied George I. to England. On the death of her husband George I. raised her to the rank of Countess of Darlington. There is evidence to show that George I. recognised the kinship between him and Lady Darlington, but she was generally supposed to be his mistress. The precise relationship must always remain a mystery.
