Maria Clementina, reported by Horace Walpole to have been "lively, insinuating, agreeable, and enterprising," had encountered, soon after her marriage with James, the too frequent fate of many who were sacrificed to royal marriages. She had quickly perceived that her influence was inferior to that of the Prince's favourites: she was shortly made aware of his infidelities: she became jealous, without affection; and her disappointment in her consort was that of a proud, resentful woman, to whom submission to circumstances was a lesson too galling to be learned. The Prince, after the fashion of his forefathers, was governed by favourites: like Charles the First, he had his Buckingham and his Strafford; and his miniature Court was rent with factions. But the Chevalier had neither the purity of Charles the First, nor the charm of character which gilded over the vices of Charles the Second. His household was an epitome of the worst passions; and his melancholy aspect, his want of dignity and spirit, his bigotry and even his unpopular virtue of economy, cast a gloom over that turbulent region. It was bitterly, but perhaps truly said of him, "that he had all the superstition of a capuchin, but none of the religion of a Prince."[165] Like most of his immediate family, his character deteriorated as he grew older. He did not rise under the pressure of adversity; and his timid, irresolute nature was crushed by the effects of his cruel situation. Colonel John Hay, of Cromlix, the brother of the Earl of Mar's first wife, and of George, seventh Earl of Kinnoul, succeeded in obtaining mastery over his subdued nature. The lady of Colonel Hay, Margery, the third daughter of Viscount Stormont, was said, also, to have possessed her own share of influence over the mind of the Chevalier. Of the real existence of any criminal attachment between the Prince and Mrs. Hay, there is, however, considerable doubt; and it has been generally regarded as one of those amours raised for a purpose, during the continuance of a fierce contention for power. Clementina had also her favourites; and a certain Mrs. Sheldon, who had had the charge of Prince Charles Edward, had acquired her confidence. This choice was peculiarly infelicitous. Mrs. Sheldon was reported to be about as unworthy a favourite as the unhappy Princess could have selected. According to Colonel Hay, she was the mistress of General Dillon, one of the most ardent adherents of the Stuarts, and the spy of the Earl of Mar.[166] For four or five years, nevertheless, after Prince Charles's birth, she continued to be his governess, and to sway the feelings of his mother, in the same manner as confidants and dependants usually direct the angry passions of their mistresses into the most dangerous channels. During the height of Colonel Hay's favour, the confidence of the Chevalier in Lord Mar visibly declined, as appears in the following letter to one of his adherents in Scotland.
