Lady Mary Pierrepoint, eldest daughter of the Duke of Kingston, was born in 1690, and gave, in her early youth, such indications of a studious disposition, that she was initiated into the rudiments of the learned languages along with her brother. Her first years appear to have been spent in retirement, and yet her first letters indicate a great relish for that talent and power of observation, by which she afterwards became so famous and so formidable. These letters were addressed to Mrs Wortley, the mother of her future husband, and, along with a good deal of girlish flattery and affectation, display such a degree of easy humour and sound penetration, as is not often to be met with in a damsel of nineteen, even in this age of precocity. "My knight-errantry," she says, "is at an end, and I believe I shall henceforth think freeing of galley-slaves and knocking down windmills more laudable undertakings than the defence of any woman's reputation whatever. To say truth, I have never had any great esteem for the generality of the fair sex, and my only consolation for being of that gender has been the assurance it gave me of never being married to any one among them." But, in the course of this correspondence with the mother, she appears to have conceived a very favourable opinion of the son. Her ladyship, though endowed with a very lively imagination, seems not to have been very susceptible of violent or tender emotions, and to have imbibed a very decided contempt for sentimental and romantic nonsense, at an age which is commonly more indulgent. Married to Mr Wortley in 1712, she entered upon a gay life; but she does not appear to have been happy. We have no desire to revive forgotten scandals, but it is a fact which cannot be omitted, that her ladyship went abroad without her husband, on account of bad health, in 1739, and did not return to England till she heard of his death in 1761. Whatever was the cause of their separation, there was no open rupture, and she seems to have corresponded with him very regularly for the first ten years of her absence; but her letters were cold without being formal, and were gloomy and constrained when compared with those that were spontaneously written to show her wit or her affection to her correspondents.
