The couple was buried together at the Basilica of Saint Denis on 23 February 1712. Their son, the Duke of Brittany succeeded as Dauphin, but he died the following March from the measles. The only child to survive the epidemic was the future Louis XV who was locked inside his apartments with his governess Madame de Ventadour to avoid being bled to death by doctors like his elder brother had been. Madame de Ventadour was renowned for having saved the infant Louis XV's life. Louis XV subsequently named his fourth daughter "Marie Adélaïde" in his mother's honour.
