William of Tyre (Continuator) names her and specifies her parentage. A continuator of Caffaro records the death in 1192 of "Conrado marchionis Montidferrati" leaving "uxore sua pregnante, ex quo nata est unica filia Maria", which indicates that Maria must have been born in summer 1192, therefore after her mother's second marriage. She was known as "la Marquise", from her father's rank.
She succeeded her mother in 1206 as MARIE Queen of Jerusalem, under the regency of Jean of Ibelin Lord of Beirut. Her marriage was arranged by Philippe II King of France, who gave her husband a dower of 40,000 silver pounds, a sum which was equalled by Pope Innocent III. She was crowned with her husband 3 Oct 1210 at Tyre.
William of Tyre (Continuator) records her death in childbirth within two years of her marriage. 2
