The King's mother, the Electress Sophia, had commented on her to Mrs.Howard: "Look at that mawkin, and think of her being my son's passion." If a family portrait, now in the possession of Count Werner Schulenburg, may be trusted, she was what is called "a fine figure of a woman"; she had blue eyes and fair hair.

She was so tall that she was nicknamed in England "the May-pole." She was certainly determined to make the most of her opportunities, and the more eager because at the beginning of the reign she was very doubtful whether George I would not have hurriedly to retire to Hanover for good and all.
So doubtful of the likelihood of the duration of the Hanoverian line in this country was she that at first she declined to accompany the Elector, and she only changed her mind when she found the Baroness von Kielmansegg had decided to go to England.

She was in high favour with George, and took every advantage of her influence.

She left an immense fortune, which was acquired in ways into which an eulogistic biographer of the lady would not enquire.

Certainly, she received for her good offices large sums of money from the promoters of the South Sea Act, she accepted bribes to secure peerages, and, it is said on the authority of Sir Robert Walpole, that Bolingbroke presented her with L11,000 to endeavour to secure his restoration to the royal favour.
