François III de La Rochefoucauld
François III, Count of La Rochefoucauld, prince of Marcillac, count of Roucy and baron of Verteuil (1521 – 24 August 1572) was a French courtier and soldier, serving as gentleman-in-ordinary to the king's chamber. He was a friend of Charles de Téligny and Louise de Coligny, serving as one of the witnesses to their marriage, whilst his humour and intelligence rendered him a favourite of Henry II of France and Charles IX of France. He is also notable as one of the Protestant leaders killed in the St. Bartholomew's Day massacre.
