The sisters of Marie-Louise O'Murphy are also known for being involved in prostitution. Jean Meunier, police inspector who was in charge of monitoring girls and women dedicated to this work, dedicated several pages to the O'Murphy sisters in the diary that he wrote from 1747 and in a report made in 1753 for his superior Nicolas René Berryer, "lieutenant général de police". On 12 May 1753 Meunier dedicated three pages to the five O'Murphy sisters: Marguerite, Brigitte, Madeleine, Victoire and Marie-Louise. About Marguerite and Madeleine (nicknamed Magdelon), he notes that they have their "campaigns in Flanders" following the French army, but before their departure would often be in the company of their sister Victorie and "the Richardot, the Duval, the Beaudouin, the Fleurance and others women of the world". About Brigitte, Meunier wrote that "she always stayed with her parents and she wasn't either brilliant or noisy"; however, he concluded that "despite her ugliness we are sure that she wasn't an innocent girl".
