  Research Notes:

The Chronicle of Ralph of Coggeshall records the marriage of King Philippe in 1193 and "sororem regis Daciæ…Ingelburgh" and his repudiation of her after the wedding. The Balduini Ninovensis Chronicon records the marriage of "Philippus [rex]" and "filiam…regis Dano", recording that he repudiated her after 8 days and imprisoned her. She was known as Isambour in France.

She was consecrated Queen of France 15 Aug 1193, but during the ceremony King Philippe "by the devil's suggestion, began to be horrified, to tremble and turn pale at the sight of her". The chronicler William of Newburgh reported that the king's aversion to Isambour was reported to be due to the fetid smell of her breath or to some hidden deformity. King Philippe disavowed her, imprisoned her at Cysoing and procured an annulment from prelates at the synod of Compiègne, although this was not recognised by the Pope. A charter dated 1193 records that Etienne Bishop of Tournai requested Guillaume Archbishop of Reims to protect "Reginam" who had sought protection in Cysoing abbey. Protracted correspondence with successive Popes ensued, the dispute being complicated by the king's bigamous third marriage. King Philippe's refusal to restore Isambour eventually resulted in Pope Innocent III's interdict on France 13 Jan 1200. The king restored Isambour as queen from Apr 1213, although it is likely that the couple did not live together, Isambour living on her dower lands near Orléans.

The Chronicle of Alberic de Trois-Fontaines records the death in 1237 of "senior regina Francie…Guineburgis sive Indeburgis de Dacia" specifying that she was "domna Aurelianensis". The necrology of the Eglise Cathédrale de Paris records the death "IV Kal Aug" of "regina Ysenburgis…uxor regis Francorum Philippi". ¹
