Margaret, Marchioness of Namur (ca. 1194 - 17 Jul 1270) was the daughter of Peter II of Courtenay and Yolanda of Flanders.
Margaret (called Sybille in some sources) married Raoul lord of Issoudun in 1210. She succeeded her husband as Lady of Châteauneuf-sur-Cher and Mareuil-en-Berry in 1216. Soon after the death of her first husband she married Henry I, Count of Vianden in 1216. Henry was the son of Frederic III, Count of Vianden and Mechtild of Neuerburg.
Margaret became Marchoness of Namur after the death of her brother Henry II, Marquis of Namur in 1229. Margaret and her husband Henry of Vianden ruled Namur until 1237 when they had to transfer Namur to Margaret's brother Baldwin II of Courtenay. [1]
After the death of her husband in 1252, Margaret entered a convent in Marienthal near Luxembourg and became a nun. She died in Marienthal on 17 July 1270 and was buried there.[2]
Margaret and Henry had two children [3]:
Frederic of Vianden. Frederic died in 1247 (5 years before his father). Frederic married a daughter of Henry III, Count of Ardennes, and had a son named Henry.
