Jacquetta of Luxembourg, daughter of Pierre de Luxembourg (b. 1416)
Jacquetta of Luxembourg, Countess Rivers (1415/16 – 30 May 1472) was the eldest daughter of Peter I of Luxembourg, Count of Saint-Pol, Conversano and Brienne, and his wife Margaret of Baux (Margherita del Balzo of Andria). She was a prominent, though often overlooked, figure in the Wars of the Roses. Through her short-lived first marriage to the Duke of Bedford, brother of King Henry V, she was firmly allied to the House of Lancaster. However, following the emphatic Lancastrian defeat at the Battle of Towton, she and her second husband Richard Woodville sided closely with the House of York. Three years after the battle and the accession of Edward IV of England, Jacquetta's eldest daughter Elizabeth Woodville married him and became Queen consort of England. Jacquetta bore Woodville 14 children and stood trial on charges of witchcraft, of which she was exonerated.
