"Henrietta of England (16 June 1644 O.S. [26 June 1644 N.S.]) – 30 June 1670) was the youngest daughter of King Charles I of England, Scotland and Ireland and Henrietta Maria of France.
Fleeing England with her mother and governess at the age of three, Henriette moved to the court of her first cousin, King Louis XIV of France, where she was known as Minette. She married her other cousin Philippe I, Duke of Orléans and became known Fils de France, but their relationship was marked by frequent tensions over common suitors Very clever, Henrietta was instrumental in negotiating the Secret Treaty of Dover against the Dutch Republic in June 1670, the same month as her unexpected death. Jacobite claims to the British throne following Henry Benedict Stuart's death descend from her daughter Anne Marie, Queen of Sardinia." - (en.wikipedia.org 29.12.2020)
