Marguerite de Valois, la demoiselle de Belleville, also known as Marguerite bâtarde de France (1407 – January 1458) was the illegitimate daughter of King Charles the Mad and his beloved mistress Odette de Champdivers. She was their only child.
Marguerite was legitimated in January 1428 by Charles VII of France, her half-brother.[1] He gave her a very ample dowry and married her to the Seigneur of Belleville and Montaigu. The wedding was held on May 3 of that same year in Poitou. Her husband the Seigneur was Jean III de Harpedenne (or Harpedanne, Harpedane, Harpedène, etc.), son of Jean II de Harpedenne and his wife Jeanne de Mussidan. Some sources claim that she was married under the name of Marguerite de Falots.
Claude de Belleville, the last of their descendants, was killed in the Battle of Coutras on October 20, 1587 under the reign of Henry III. The poet Jacques Bereau wrote his epitaph. His father was Charles Harpedenne, knight, lord of Belleville, Chantonnay, Sigournais, Puybelliard, Beaulieu, Saint-Flayve, La Roche-sur-Yon, etc., knight of the order of the King, and captain of 50 men in arms.
