The Genealogica Comitum Flandriæ Bertiniana names (in order) "Iohannam et Margaretam" as the two daughters of "Balduinus". She succeeded her father as JEANNE Ctss of Flanders and Ctss de Hainaut in Feb 1206 when news of his death reached Flanders, under the regency of her uncle Philippe Marquis de Namur. The latter agreed to the demand of Philippe II King of France to send the countess and her sister to Paris to be educated. King Philippe arranged her first marriage. The De Rebus Hispaniæ of Rodericus Ximene s records the marriage of "Ferdinandum", other son of "Rex…Sancius", and "Flandriæ Comitissam". While returning to Flanders after her marriage, she and her husband were captured by Louis, son of King Philippe II, who occupied Aire and Saint-Omer, the occupation being ratified by the Treaty of Pont-à-Vedin 25 Feb 1212 as the price for their release. After her husband's capture in 1214, Philippe II King of France forced on her the Treaty of Paris 24 Oct 1214, under which major fortresses in southern Flanders were destroyed, property restored to French partisans, and Flanders in effect ruled from Paris. King Philippe refused to negotiate her husband's release unless she agreed to the annulment of her marriage and remarriage to Pierre "Mauclerc" Duke of Brittany. Civil war followed the appearance in 1224 of a hermit who claimed to be Jeanne's father returned from captivity and subsided only after his execution following a confrontation with Louis VIII King of France 30 May 1225. She negotiated the Treaty of Melun in 1226 under which her husband was returned on payment of 50,000 livres ransom. The Genealogica Comitum Flandriæ Bertiniana names "Thome fratri comitis Sabaudie" as husband of "Iohanna", whom she married after the death of "Ferrandus". The Annales Blandinienses record the marriage in 1237 of "Iohannam comitissam Flandrie" with "Thomas avunculus reginarum Francie et Anglie".
The Annales Blandinienses record the death in 1244 of "Iohanna comitissa" and her burial at "Market". The Necrologio Sanctæ Waldetrudis records the death "Non Dec" of "Iohanne comitisse Flandrie et Hanoie".
