Henriette Anna wuchs bei ihrer Mutter Henriette Maria in Frankreich auf und wurde im katholischen Glauben erzogen. Sie war die Lieblingsschwester ihres ältesten Bruders, des englisch-schottischen Königs Karl II. Stuart, der sie liebevoll "Minette" nannte. Am 29. April 1670 schrieb Karl II. z. B. folgenden Brief an seine Minette: "I wrote to you last week, and meant to send my letter in Janton's packet, but she had already closed hers, so I had to give my letter to Mason. I have received yours of the 23rd, which is so full of marks of affection that I know not how to find words in which to express my joy. In return, I must assure you that I love you as much as possible, and that neither absence, nor any other cause will alter the affection I have promised to bear you, in the smallest degree. Never fear that others who are present shall get the advantage over you, for, believe me, no one can share the love I cherish for you. ... If you only knew how often we [Karl II. und Janton [Geliebte von Karl II.?; sie lebte bei ihm und schien eine Sängerin gewesen zu sein] talk of you, and wish you were here, you would understand how much I long to see you, and do me the justice to believe that I am entirely yours." (in: Julia Mary Cartwright Ady: Madame, a life of Henrietta, daughter of Charles I. and Duchess of Orleans, id., pp. 54-55).
"Henrietta [Anna] was naturally quick and clever, fond of reading, and taking delight in music and poetry. She sang well, played the guitar and harpsichord with considerable skill, and danced with a grace and elegance that attracted general attention, in those days when dancing was looked upon as an important part of a lady's education. ... In her own home she was the pet and plaything of the whole household, especially of her eldest brother Charles, whose affection for his little sister was noticed by English residents at Paris, during the years which he spent in France. Those early days saw the foundation of that warm and constant love between brother and sister which was to last to the end of Henrietta's life, and was probably the deepest and strongest element in Charles II.'s fickle nature. ... Another and more important personage, with whom the English Princess early became a great favourite, was her aunt, the Queen-mother of France. Anne of Austria invariably treated her young niece with the greatest kindness. ... she would often come herself to the Palais Royal, and take her back with her to share in the amusements of her cousins, King Louis [XIV.] and his brother Philippe, the young Duke of Anjou." (in: Julia Mary Cartwright Ady: Madame, a life of Henrietta, daughter of Charles I. and Duchess of Orleans, id., pp. 32-33).
Henriette Anna, beschrieben von Madame de Motteville zum Zeitpunkt ihrer Heirat mit Philippe I. dem Herzog von Orléans, am 31. März 1661, die sie sehr gut kannte: "The Princess of England was rather tall; she had grace, and her figure, though it was not without defects, did not then seem as spoilt as it really was. Her beauty was not the most perfect; but her whole person, though far from well made, was nevertheless, through her manner and charm, altogether agreeable. Her complexion was very delicate and very white, mingled with a natural rosiness, comparable to roses and jessamine. Her eyes were small, but soft and brilliant; her nose was not ugly; her lips were red, and her teeth were as white and fine as one could wish; but her face was too long, and her thinness seemed to threaten her beauty with a speedy end. She dressed and wore her hair in a style that suited her whole person; and as there was something in her that made itself loved ... It was already visible that she had ideas and reason; and in spite of her youth, which until then [im Jahr 1661] had concealed her from the public, it was easy to judge that when she found herself on the great stage of the Court of France she would surely play one of the leading rôles." (in: Memoirs of Madame de Motteville, Volume 3, id., pp. 244-245).
Henriette Anna, beschrieben von ihrer Zeitgenossin Madame de Brégis im Juni 1658: "To begin with her height, I must tell you that this young Princess is still growing, and that she will soon attain a perfect stature. Her air is as noble as her birth, her hair is of a bright chestnut hue, and her complexion rivals that of the gayest flowers. The snowy whiteness of her skin betrays the lilies from which she sprang. Her eyes are blue and brilliant, her lips ruddy, the throat beautiful, her arms and hands well made. Her charms show that she was born on a throne, and is destined to return there. Her wit is lively and agreeable. She is admired in her serious moments and beloved in her most ordinary ones; she is gentle and obliging, and her kindness of heart will not allow to laugh at others, as cleverly as she could, if she chose. She spends most of her time in learning all that can make a princess perfect, and devotes her spare moments to the most varied accomplishments. She dances with incomparable grace, she sings like an angel, and the spinet is never so well played as by her fair hands. All this makes the young Cleopatra [Henriette Anna] the most amiable Princess in the world, and if Fortune once unties the fold that wraps her eyes, to gaze upon her, she will not refuse to give her the greatest of earth's glories, for she deserves them well [die Autorin hofft, Henriette Maria wird ihren Cousin, den französischen König Ludwig XIV. heiraten]. I wish them for her, more passionately than I can say." (in: Julia Mary Cartwright Ady: Madame, a life of Henrietta, daughter of Charles I. and Duchess of Orleans, id., pp. 49-50).
Henriette Anna, beschrieben von Julia Cartwright Ady: "And in spite of the vivacity and sparkle which she inherited from her mother, her character, on the whole, was more of a Stuart than of a Bourbon. She possessed, in a prominent degree, the distinctive qualities of her illustrious ancestors. She had their remarkable abilities and their engaging manners, their love of culture and refined taste in art and literature. She had the same natural gaiety, the same love of amusement, the same scorn for conventionalities, the same impatience of etiquette and ceremonial. Her actions display the same impetuous feeling and carelessness of appearances, together with the same generous warmth of heart. At the same time, her character is plainly marked by that deeper and more serious vein, that strain of thoughtful and tender melancholy which was common to the best of the Stuarts. Above all, Henrietta possessed, in a supreme measure, that gift of drawing out sympathy and inspiring devotion in those about her, which was so striking a characteristic of her ill-fated race. She had many rivals, and not a few enemies, but no one was more faithfully served and more passionately beloved, or more deeply and enduringly lamented." (in: Julia Mary Cartwright Ady: Madame, a life of Henrietta, daughter of Charles I. and Duchess of Orleans, New York 1901, pp. 1-2).
"The Princess [Henriette Anna Stuart] possessed an admirable admixture of grace and beauty, wit being allied to great affability and good-nature; to all these natural gifts she added a capacity and intelligence such as one might desire sovereigns to possess. Her coquetry was mere amiability; of that I [Madame de Montespan, die Geliebte von Ludwig XIV.] am convinced. Being naturally vain, the Prince [Philippe I., Herzog von Orléans], her husband, made great use at first of his consort's royal coat-of-arms. It was displayed on his equipages and stamped all over his furniture. 'Do you know, madame,' quoth he gallantly, one day, 'what made me absolutely desire to marry you? It was because you are a daughter and a sister of the Kings of England. In your country women succeed to the throne, and if Charles the Second and my cousin York were to die without children (which is very likely), you would be Queen and I should be King.' [Was nicht stimmt, es gab immer noch die Töchter ihres Bruders Jakob II., des Herzogs von York, Mary (1662-1694) und Anne (1665-1714), die tatsächlich Königinnen von Großbritannien wurden]." (in: Memoirs of Madame la Marquise de Montespan – Being Historic Memoirs of the Court of Louis XIV, Volume 1, p. 56).
