The term "Petite maîtresse" (little mistress) was given to Louis XV's mistresses that were not formally presented at court, and unlike the official mistress ("maîtresse-en-titre") did not have an apartment in Palace of Versailles. Generally recruited by the King's valets in Paris surroundings, if their affair lasted more than a single night, they were placed in a group of houses in the district of Parc-aux-Cerfs in Versailles, or close to other royal residences. Marie-Louise O'Murphy resided there for two years, from 1753 to 1755.
