Letztendlich heiratete Ludwig XV., der als außergewöhnlich gutaussehender Mann beschrieben wurde, dem die Frauenherzen nur so zuflogen, am 5. September 1725 die jüngere Tochter des ehemaligen polnischen Königs Stanislaus Leszczynski (1677-1766), Maria oder Marie (1703-1768), die fast sieben Jahren älter als er war. Sie schenkte ihm folgende zehn Kinder: 1. und 2. die Zwillinge Louise Elisabeth (1727-1759) und Anne Henriette (1727-1752); 3. die Tochter Marie-Louise (1728-1733); 4. den Sohn Ludwig Ferdinand (oder Louis Ferdinand) (1729-1765); 5. den Sohn Philippe (1730-1733); 6. die Tochter Marie Adelaide (1732-1800); 7. die Tochter Victoire Louise Marie Thérèse (1733-1799); 8. die Tochter Sophie Philippine Elisabeth Justine (1734-1782); 9. die Tochter Marie Thérèse Felicite (1736-1744) und 10. die Tochter Louise Marie (1737-1787). Aus seinen zahlreichen außerehelichen Verhältnissen gingen noch mindestens 13 weitere Kinder hervor.
"... Louis XV was extremely attractive. He was tall and handsome, he had a most caressing look, a curious husky voice which nobody ever forgot who had once heard it, and a sexy moodiness of manner irresistible to women; the haughty air, which came in reality from shyness, in no way detracted from his charm. ... He was a religious man, a family man at heart." (in: Nancy Mitford: Madame de Pompadour, id., p. 2). "While not exactly in love with Maria Leczinska, he [Ludwig XV.] now [als jene gegen Ende des Jahres 1726 zum ersten Mal schwanger geworden war] felt tied to her by more than just protocol. This orphan [Ludwig XV.], this adolescent whose closest relatives were the unappealing ducs d'Orléans and de Bourbon, wanted a family of his own more than anything in the world. As soon as the Queen showed signs of providing him with children, she earned his deep and lasting affection. ..." (in: Olivier Bernier: Louis the beloved – The Life of Louis XV, id., p. 68).
"... Louis XV behaved very much like the rest of his people. He had been a good husband for several years, and he always remained a kind and faithful friend to his wife. ... he was a devoted father ... the King loved the Dauphin dearly, spent time with him, gave him numerous personal presents, took pride in his achievements, oversaw his education and watched his health with the deepest concern. In 1738, for instance, the nine-year-old boy was suffering from an abscess at the juncture of cheek and jaw which had to be incised. Anesthesia had yet to be invented, so the operation was dreadfully painful. Against all tradition, the King insisted on being present, but when he heard his son's shrieks, he began to shake and grew so pale that his attendants expected him to faint. In one respect, however, and in spite of his obvious reluctance, he behaved like an eighteenth-century father. At Fleury's request, and for reasons of economy, it was decided that five of his seven daughters would be sent off, for a few years, to the convent of Fontevrault, thus obviating the need for costly separate households. The two oldest girls, Mesdames Elisabeth and Henriette, who were eleven, and thus approaching marriageable age, were allowed to stay. Then, when the King announced his decision, the six-year-old Madame Adélaide burst into sobs, flung herself at her father's feet and begged not be sent away. Unable to resist the child's tears, Louis agreed to let her stay, so in May 1738 Mesdames Victoire, Sophie, Félicité and Louise went off." (in: Olivier Bernier: Louis the beloved – The Life of Louis XV, id., p. 93).
"... the daughters who, at Fleury's request, had been sent off to Fontevrault [im Jahr 1738], at last came back to Versailles. They were fewer in number [Marie Thérèse Felicite war am 28. September 1744 gestorben] ... but the King was overjoyed to have them near him again. Madame Victoire, who arrived in the summer of 1748, was followed, in October 1750, by Mesdames Sophie and Louise. 'The King went to greet them with M. le Dauphin [seinem Sohn Louis Ferdinand] and Madame Victoire,' Mme de Pompadour wrote her brother. 'I had the honor of following him. In truth, nothing is more touching than these meetings. The King's tenderness for his children is beyond anything and they respond to it wholeheartedly.'" (in: Olivier Bernier: Louis the beloved – The Life of Louis XV, id., p. 158).
