Anne de L'Enclos was born in Paris in 1615. She was the daughter of Monsieur de L'Enclos, a gentleman of Touraine, and of his wife, a member of the family of the Abra de Raconis of the Orléanois.
It would not be easy to find characteristics more diverse than those distinguishing this pair. Their union was an alliance arranged for them—a mariage de convenance . Diametrically opposite in temperament, Monsieur was handsome and distinguished-looking; while the face and figure of Madame were ordinary. She was constitutionally timid, and intellectually narrow, devoted to asceticism, and reserved in manner. She passed her time in seclusion, dividing it between charitable works, the reading of pious books, and attendance at Mass and the other services of the Church. Monsieur de L'Enclos, on the other hand, was a votary of every pleasure and delightful distraction the world could afford him.
