Who dated Henry I, Duke of Guise?

Henri I de Lorraine, Duke of Guise, Prince of Joinville, Count of Eu (31 December 1550 – 23 December 1588), sometimes called Le Balafré ('Scarface'), was the eldest son of François, Duke of Guise, and Anna d'Este. His maternal grandparents were Ercole II d'Este, Duke of Ferrara, and Renée of France. Through his maternal grandfather, he was a descendant of Lucrezia Borgia and Pope Alexander VI.

A key figure in the French Wars of Religion, he was one of the namesakes of the War of the Three Henrys. A powerful opponent of the queen mother, Catherine de' Medici, Henri was assassinated by the bodyguards of her son, King Henry III.

Charlotte de Beaune Semblançay, Viscountess of Tours, Baroness de Sauve, Marquise de Noirmoutier (26 October 1551 – 30 September 1617) was a French noblewoman and a mistress of King Henry of Navarre, who later ruled as King Henry IV of France. She was a member of queen mother Catherine de' Medici's notorious "Flying Squadron" (L'escadron volant in French), a group of beautiful female spies and informants recruited to seduce important men at court, and thereby extract information to pass on to the Queen Mother.
