This story is, as a matter of fact, not far removed from the truth. It omits, however, the fact that Lord Peterborough, then about sixty years of age, had married Anastasia Robinson in 1722; but the marriage was secret, although Lady Oxford was present at the ceremony, and it was not made public until thirteen years later, although long before there were many who suspected it. He died in the same year that the announcement was made. His widow survived him by a score of years.

Sir Godfrey Kneller had a house at Twickenham, and, at the instigation of Pope, sat to him for her portrait, upon which the following lines (generally ascribed to Pope) were written:

"The playful smiles around the dimpled mouth.
That happy air of majesty and truth;
So would I draw (but oh! 'tis vain to try,
My narrow genius does the power deny;)
The equal lustre of the heav'nly mind,
Where ev'ry grace with every virtue's join'd;
Learning not vain, and wisdom not severe,
With greatness easy, and with wit sincere;
With just description show the work divine,
And the whole princess in my work should shine."

Mrs. Howard, afterwards the Countess of Suffolk, was a neighbour from 1723, when the Prince of Wales, whose mistress she was, provided her with funds for the purchase of Marble Hill. However, though, of course, she and Lady Mary were acquainted, there was at no time any intimacy between them. Lady Mary, in fact, does not appear to have liked Henrietta Howard. At least she on more than one occasion tittle-tattled about her. "The most surprising news is Lord Bathurst's assiduous court to their Royal Highnesses, which fills the coffee-houses with profound speculations. But I, who smell a rat at a profound distance, do believe in private that Mrs. Howard and his lordship have a friendship that borders upon 'the tender.'

"And though in histories, learned ignorance
Attributes all to cunning or to chance,
Love in that grave disguise does often smile,
Knowing the cause was kindness all the while."

So Lady Mary wrote to Lady Mar in 1724, and shortly after returned to the subject in another epistle: "You may remember I mentioned in my last some suspicions of my own in relation to Lord Bathurst, which I really never mentioned, for fifty reasons, to anyone whatsoever; but, as there is never smoke without some fire, there is very rarely fire without some smoke. These smothered flames, though admirably covered with whole heaps of politics laid over them, were at last seen, felt, heard, and understood; and the fair lady given to understand by her commanding officer, that if she showed under other colours, she must expect to have her pay retrenched. Upon which the good Lord was dismissed, and has not attended the drawing-room since. You know one cannot help laughing, when one sees him next, and I own I long for that pleasurable moment."

To Twickenham came Philip, Duke of Wharton, and leased a villa, later called The Grove, at the farther end of the hamlet from London. Of all the lads of the village there was none for wildness like unto him. Born in 1698, and therefore nine years younger than Lady Mary, he had at an early age made himself conspicuous by unbridled excesses. Soon after the death of his father, Thomas, first Marquess of Wharton, in 1715, his conduct created so much scandal at home, that his guardians sent him abroad in the custody of a tutor. To the horror of that unfortunate person, his charge enrolled himself as an adherent of the Pretender, and went to pay his respects at Avignon. The Duke had talent beyond the ordinary. He could write fairly well, make an excellent speech, and had a keen sense of wit. When he went to Paris, the British Ambassador, Lord Stair, took it upon himself to give this madcap some sound advice. He extolled the virtues of the late Marquess of Wharton, and, "I hope," he said, "you will follow so illustrious an example of fidelity to your Prince and love to your country." "I thank your Excellency for your good counsel," replied the visitor courteously, "and as your Excellency had also a worthy and discerning father, I hope that you will likewise copy so bright an example, and tread in all his footsteps,"—an effective though a brutal rejoinder, for the first Lord Stair had betrayed his Sovereign. Young Wharton, on his return, however, showed by his conduct that his visit to Avignon had been little more than a prank, for while he had accepted a dukedom from the Pretender, he, in 1718, being still a minor, accepted a dukedom from the British Sovereign—the single instance of such a dignity being conferred upon a minor.

Wharton, who did everything in haste, had in his seventeenth year eloped with Martha, daughter of Major-General Richard Holmes, and married her in the Fleet on March 2, 1715. As was only to be expected from a person so volatile he from the beginning neglected his wife; but, as is put quaintly in that unreliable work, Memoirs of a Certain Island adjacent to the Kingdom of Utopia, which was concocted by Mrs. Eliza Haywood, "after some years of continu'd extravagance, the Duke, either through the natural Inconsistency of his Temper, or the Reflection how much he had been drawn in by his unworthy Companions to embezel his Estate … began to think there were Comforts in Retirement; and falling into the Conversation of the sober part of Mankind, more than he had done, was persuaded by them to take home his Dutchess…. He brought her to his House; but Love had no part in his Resolution. He lived with her indeed but she is with him as a Housekeeper, as a Nurse." The relations were, however, more intimate than Mrs. Haywood believed, for in March, 1719, a son was born to them.

"The Duke of Wharton has brought his Duchess to town, and is fond of her to distraction; in order to break the hearts of all other women that have any claim on him," Lady Mary wrote to Lady Mar. "He has public devotions twice a day, and assists at them in person with exemplary devotion; and there is nothing pleasanter than the remarks of some pious ladies on the conversion of such a sinner."

The letter from which the above passage is an extract must have been written not later than the early spring of 1720, for after that date the Duke and Duchess of Wharton did not again live together. The immediate cause of the separation was that Wharton had forbidden his wife to come to London where small-pox was raging at the time. She, however, whether irked by the dulness of the country, or thinking by her presence to guard her husband against those temptations to which he was prone, followed him to the town, where the infant sickened of the epidemic and died. After one great scene, they never met again.
