Trie

The de Trie were a knightly family of the Vexin, taking their name from Trie-en-Vexin and descending from a younger line of the viscounts of Chaumont-en-Vexin. Galon II was constable in 1085 and Hugues I served as constable of France under Louis VI.

Jean I, lord of Trie and Mouchy, married Alix of Dammartin, sister of the count of Boulogne. Their son Mathieu inherited the County of Dammartin in 1262, and his descendants held it through the fourteenth century; Jean I of Dammartin fell at Courtrai in 1302, and the line ended with the countess Blanche around 1400.

Renaud de Trie and his son Mathieu III were both marshals of France, Mathieu commanding Tournai in the early Hundred Years' War. Guillaume became archbishop of Reims and crowned Philip VI in 1328.
