an endowment of £100 annually to the Collegial Church of Notre-Dame-et-Saint-Laurent for a mass to be celebrated there on 17 June each year in his memory. Their eldest son, Philippe, died on 23 December in the same year and is also buried in Eu. Jointly with her widowed sister-in-law, Jeanne of Thouars, Marie was appointed guardian of the three surviving children of her marriage with Philippe: Charles, Bonne and Catherine. Aged about three, Charles succeeded his father as Count of Eu. His revenues were held for him until he came of age by three trustees: Marie herself, her father, and her uncle Philip the Bold, Duke of Burgundy. Duchess consort of Bourbon Marie married her third husband John of Bourbon at the "King's Palace" (the Palais de la Cité) in Paris on 21 June 1401. The contract had been signed at Paris on 27 May 1400 after complex negotiations. She bore him three children.

According to Patricia Stirnemann, referencing Saint-Jean Boudin, the scene, although not painted until about 1410, depicts the engagement of Marie with John of Bourbon in 1401. Raymond Cazelles disputes this, arguing that the couple are Marie's niece Bonne of Armagnac and Charles, Duke of Orléans, who were to marry in 1411. A May Day celebration among nobles takes place in the foreground of the illustration for the month of May. Details appear to confirm that the house of Bourbon is represented. Both Cazelles and Stirnemann believe that the woman seen in the foreground, riding on a white horse and wearing a large white headdress, is Marie on the occasion of her marriage on 21 June 1401. These scholars do not agree as to which of the
