Aubrey de Vere, the twentieth Earl of Oxford, was the last of his house who held that title, but the one who held it the longest, namely, seventy years, from 1632 to 1702. Aubrey de Vere despised the old maxim, "Noblesse oblige." He lived a roystering life, kept a roystering house, and was addicted to hard drinking, rough words, and unseemly brawling and sword-slashing in his cups. The young earl made love, after the fashion of the day and the man, to Mrs. Davenport, but he might as well have made love to Diana; and it was not till he proposed marriage that the actress condescended to listen to his suit. The lovers were privately married, and the lady was, in the words of old Downes, "erept the stage." The honeymoon, however, was speedily obscured; Lord Oxford grew indifferent and brutal. When the lady talked of her rights, he informed her that she was not Countess of Oxford at all. The apparent reverend gentleman who had performed the ceremony of marriage was a trumpeter, who served under this very noble Lord in the King's own regiment of cavalry. The forlorn fair one, after threatening suicide, sought out the King, fell at his feet, and demanded justice. The award was made in the shape of an annuity of £300 a year, with which "Lord Oxford's Miss," as Evelyn calls her, seems to have been satisfied and consoled; for Pepys, soon after, being at the play, "saw the old Roxalana in the chief box, in a velvet gown, as the fashion is, and very handsome, at which I was glad."
As for Miss Mary Davies, it is uncertain whether she was the daughter of a Wiltshire blacksmith, or the less legitimate offspring of Thomas Howard, the first Earl of Berkshire, or of the earl's son--not the poet, but the colonel. However this may be, Mary Davies was early on the stage, where she danced well, played moderately ill, announced the next afternoon's performance with grace, and won an infamous distinction at the King's hands, by her inimitable singing of the old song, "My lodging is on the cold ground." Then there was the publicly furnishing of a house for her, and the presentation of a ring worth £600, and much scandal to good men and honest women. Thereupon Miss Davies grew an "impertinent slut," and my Lady Castlemaine waxed melancholy, and meditated mischief against her royal and fickle lover. The patient Queen herself was moved to anger by the new position of Miss Davies, and when the latter appeared in a play at Whitehall, in which she was about to dance, her Majesty rose and left the house. But neither the offended dignity of the Queen, nor Lady Castlemaine "looking fire," nor the bad practical jokes of Nell Gwyn, could loose the King from the temporary enchantment to which he surrendered himself. Their daughter was that Mary Tudor, who married the second Earl of Derwentwater, whose son, the third earl, was the gallant young fellow who lost his head for aid afforded to his cousin, the first Pretender, in 1715. Before his death, a request was made to the Duke of Richmond, son of Charles II., by Madlle. de Querouaille, to present a memorial to the Lords in order to save the young earl's life. The Duke presented the memorial, but he added his earnest hope that their lordships would reject the prayer of it! In such wise did the illegitimate Stuarts play brother to each other! Through the marriage of the daughter of Lord Derwentwater with the eighth Lord Petre, the blood of the Stuart and of Moll Davies still runs in their lineal descendant, the present and twelfth lord.
