Heinrich, der nach seinem Großvater mütterlicherseits, dem französischen König Heinrich IV. (1553-1610), genannt worden war, war das achte Kind des englisch-schottischen Königs Karl I. Stuart (1600-1649) und seiner Gattin Henriette Maria von Frankreich (1609-1669). Er erblickte am 8. Juli 1640 das Licht der Welt und starb am 16. September 1660. Seine Mutter wollte ihn nach der Hinrichtung seines Vaters zum Kardinal erheben lassen. Heinrich hatte seinem ältesten Bruder Karl II. jedoch versprochen, nicht vom anglikanischen Glauben seines Vaters abzuweichen. "When Henry still proved difficult, she [seine Mutter] packed him off to the monastery at Pontoise ... Charles [Karl II.] was appalled when he heard; Henry's conversion 'would be the greatest misfortune that ever befell him,' he wrote to his mother. She was ruining all his chances of returning to England, for Protestants were bound to believe her attempt to convert Henry was 'done with his consent,' while any action he would take now to prevent her would 'disoblige all Catholics' and end all hopes of aid from abroad. If she did not desist, he threatened, it would 'cause a breach between them which will never be made up.' And Charles warned Henry that if he converted he would be 'not only the cause of ruining a brother who loves you so well, but also your king and country,' and then, 'you must never think to see England and me again.' ... [Heinrich wollte nie Geistlicher werden und verließ das Kloster] Returning to Paris, he informed his mother that he would obey his brother's wishes, which were 'more suitable to his inclinations and his duty.' At this, Henrietta's long-pent-up bitterness exploded. 'She would no more own him as her son,' she said; she 'commanded him out of her presence, [and] forbade him any more to set his foot into her lodgings.' When Henry knelt and asked her blessing as he left, she refused to give it. ... Before leaving Paris, he made a last attempt to heal the rift, writing her 'a very dutiful letter.' But his mother refused even to receive it. She never saw Henry again."

Über den obigen Vorfall lesen wir bei Julia Cartwright Ady: "On the young Duke's [Heinrich Stuarts] return from Pontoise, she [seine Mutter Henriette Maria] tried the effect of caresses and tears, assuring the boy of her tender affection, and promising him wealthy benefices in France, and even a Cardinal's hat, if he would only embrace the Catholic faith. But the young Duke stood firm, and, after another long conference with Abbé Montagu [katholischer Beichtvater von Henriette Maria], sent his mother word that he would never leave the Church of England. The Abbé replied, 'Then it is Her Majesty's command that you see her face no more.' It was Sunday morning, and the Queen was starting for Chaillot in her coach, when her son fell on his knees before her, and asked her farewell blessing. She turned angrily away, and the boy went back heart-broken to his own room. Montagu, seeing his distress, asked him what the Queen had said to him, upon which the young Duke replied sharply, 'What I may thank you for, sir, and what I now repeat to you. Be sure that I see your face no more.' He turned on his heel, and accompanied the Duke of York [seinen Bruder Jakob] to the English service at Sir Richard Browne's chapel. On his return he found his rooms in the Palais-Royal dismantled, and no dinner prepared for him. His servants were dismissed, his horses turned out of the royal stables. But the exiled cavaliers rallied round him. Lord Hatton gave him shelter in his lodgings, and Lord Ormonde sold his George, the last jewel that he possessed, to supply him with funds for his journey. That night the young Duke came back to the Palais-Royal, to take leave of the little sister [Henriette Anna] whom he loved so tenderly, before the Queen should have returned from vespers at Chaillot. ... So they parted, and the Duke, with his faithful companion Ormonde, set out to join the King [seinen ältesten Bruder Karl II.] at Cologne. On the way, he paid a secret visit to his sister [Maria], the Princess of Orange, who welcomed him with open arms." (in: Julia Mary Cartwright Ady: Madame, a life of Henrietta, daughter of Charles I. and Duchess of Orleans, id., pp. 30-31).
