She got out of the town in disguise, and made the best of her way in a post-chaise to Holland, from whence she embarked with the King, and arrived at the same time with him in England; which was enough to make her called his mistress, or at least so great a favourite that the whole Court began to pay her uncommon respect.
"This lady deserves that I should be a little particular in her character, there being something in it worth speaking of.

She was past forty; she had never been a beauty, but certainly very agreeable in her person when adorned with youth; and had once appeared so charming to the King, that it was said the divorce and ruin of his beautiful Princess, the Duke of Celle's daughter, was owing to the hopes her mother (who was declared mistress to the King's father, and all-powerful in his Court,) had of setting her daughter in her place; and that project did not succeed, by the passion which Madame Kielmansegg took for M.Kielmansegg, who was a son of a merchant of Hamburg, and after having a child by him, there was nothing left for her but to marry him.

Her ambitions ran mad with the disappointment, and died in that deplorable manner, leaving L40,000 which she had heaped by the favour of the Elector, to this daughter, which was very easily squandered by one of her temper.

She was both luxurious and generous, devoted to her pleasures, and seemed to have taken Lord Rochester's resolution of avoiding all sorts of self-denial.
She had a greater vivacity in conversation than ever I knew in a German of either sex.

She loved reading, and had a taste of all polite learning.
Her humour was easy and sociable.
