Notes
Marriage
She also held the post of Abbess of Romsey for five years until her abduction by Matthew of Alsace, who forced her to marry him.Marie's marriage to Matthew was annulled in 1170. This was the same year that she gave birth to their youngest daughter, Mathilde in Louvain. Following the annulment, Marie re-entered the religious life as a Benedictine nun at St. Austrebert, Montreuil, where she died on 25 July 1182 at the age of about 46.[1][2] Her former husband Matthew continued to reign as Count of Boulogne until his death in 1173, when their eldest daughter Ida succeeded as countess. Following the death of Ida's daughter, Matilda II, the county of Boulogne eventually passed to Adelaide of Brabant, daughter of Marie's second daughter, Mathilde.
