2nd da. of Enguerrand de Couci; m. (1) Alexander II of Scotland, 15 May 1239; (2) John de Brienne; bur. Newbottle.
Daughter of a Picard lord, and related to the French crown, Marie seems to have settled better in Scotland than her predecessor, and gave Alexander his desired heir and successor. She left Scotland for France after his death, in the autumn of 1250, but though she may have planned to return the following spring, she did not do so for several years; she visited York at Christmas 1251, however, when her boy-king son was knighted, then married. Squabbles between the Comyns and Durwards during Alexander's minority encouraged her return to Scotland in June 1257, with her second husband, though she had to swear to Henry III that she would do nothing to upset the government of 1255. In 1258, agreement was reached that the care of the kingdom would be in the hands of a council, in which queen Marie and John de Brienne were factionally neutral.
