According to her Wikipedia article, there were three Princesses de Conti alive at the same time: "In 1709, her husband died in Paris. In order to tell them apart after the death of their respective husbands, the dowager Princesses of Conti were given the name of Douairière preceded by a number corresponding to their time of widowhood. Their full style would then be Madame la Princesse de Conti 'number' douairière. Between 1727 and 1732, there were three dowager Princesses de Conti:
• Marie Anne de Bourbon (1666–1739), the legitimised daughter of Louis XIV and Louise de La Vallière; she was the wife of Louis Armand I, Prince of Conti. Widowed in 1685, she was known as Madame la Princesse de Conti première douairière. Her husband's title went to his younger brother, François Louis, Prince of Conti.
• Marie Thérèse de Bourbon (1666–1732), the wife of François Louis, Prince of Conti; widowed in 1709, she was known as ''Madame la Princesse de Conti seconde douairière.
