She was the daughter of Robert IV, Count of Dreux, and Beatrice, Countess of Montfort. Her father was a patrilineal descendant of King Louis VI of France, her paternal grandmother Marie de Bourbon was a cousin of Guy of Dampierre, Count of Flanders, while her mother Beatrice was the only child of Count John I of Montfort-l"Amaury and his wife Jeanne, Dame de Chateaudun.
Career
Yolande belonged to the Capetian dynasty and had close ties to other prominent noble families. Yolande succeeded her mother as suo iure Countess of Montfort. Yolande was the second wife of Alexander III, King of Scots, who married her in search of an heir.
In addition to providing an heir for the Kingdom of Scotland, Alexander"s marriage to Yolande represented a move to distance Alexander from his neighbour Edward I of England, and to emphasize Scottish independence from England.
The marriage was celebrated on 15 October 1285 at Jedburgh Abbey. Alexander died on either 18 March or 19 March 1286, after falling from his horse, while riding from his court at Edinburgh to join Yolande at Kinghorn.
