Margaret of Baux

Margaret was born in 1394, the daughter of Francis of Baux (1330 – 23 April 1422) by his third wife Sueva Orsini (1360 – c.1430).[1] a descendant of Simon de Montfort, 6th Earl of Leicester and Eleanor of England (daughter of King John of England).[2]

Her paternal grandparents were Bertrand III of Baux, Count of Andria and Squillace, and Marguerite d'Aulnay, and her maternal grandparents were Nicola Orsini, Count of Nola, Senator of Rome (27 August 1331 – 14 February 1399), and Jeanne de Sabran.

On 8 May 1405, Margaret married Peter of Luxembourg, Count of Saint-Pol,[3] of Brienne, and of Conversano (1390 – 31 August 1433), the eldest son of John of Luxembourg, Lord of Beauvoir and Marguerite of Enghien, Countess of Brienne and of Conversano, Heiress of Enghien. Peter inherited his mother's fiefs, which included the counties of Brienne and Conversano. He succeeded his aunt Jeanne of Luxembourg, Countess of Saint-Pol and Ligny, as Count of Saint-Pol in 1430. His younger brother John II of Luxembourg, Count of Ligny, an ally of the English during the Hundred Years War, received Joan of Arc as his prisoner, and subsequently sold her to the English, for 10,000 livres.

Peter and Margaret had:

• Louis of Luxembourg, Count of Saint-Pol, de Brienne, de Ligny, and Conversano, Constable of France (1418 – 19 December 1475), married firstly, in 1435, Jeanne de Bar, Countess of Marle and Soissons (1415 – 14 May 1462), by whom he had issue, and from whom descended King Henry IV of France and Mary, Queen of Scots. He married secondly, Marie of Savoy (20 March 1448 – 1475), by whom he had further issue. He was beheaded in Paris in 1475 for treason against King Louis XI.
• Jacquetta of Luxembourg (1415/1416 – 30 May 1472), married firstly in 1433, John, Duke of Bedford, and secondly, in secret, c.1436, Richard Woodville, 1st Earl Rivers, by whom she had 16 children, including Elizabeth Woodville, queen consort of King Edward IV of England. Every English monarch after King Henry VII of England descends from Jacquetta's granddaughter, Elizabeth of York, queen consort of England.
