"Louise Françoise de Bourbon, Duchess of Bourbon (1 June 1673 – 16 June 1743) was the eldest surviving legitimised daughter of Louis XIV of France and his maîtresse-en-titre, Madame de Montespan. She was said to have been named after her godmother, Louise de La Vallière, the woman her mother had replaced as the king's mistress. Before her marriage, she was known at court as Mademoiselle de Nantes.
Married at the age of 11, she became known as Madame la Duchesse, a style she kept as a widow. She was Duchess of Bourbon and Princess of Condé by marriage. She was later a leading member of the cabale de Meudon, a group centered on Louis, the Grand Dauphin, her half-brother. While her son, Louis Henri, Duke of Bourbon was Prime Minister of France, she tried to further her political influence, but to little avail." - (en.wikipedia.org 24.05.2021)
