The vidame of the day took part in the First Crusade (1095–1099). The title was held by the de Ferrières family by the 12th century. They had acquired it through marriage with the sister and heiress of the 10th vidame of the family of the lords of Étienne. Confusingly, this was an entirely different de Ferrières family to that holding the title in the 16th century. Holders included Guillaume de Ferrières (grandson of the first de Ferrières vidame, c.1150 – ?April 1204), who took part in the Third (1188–92) and Fourth Crusades (1201–4), and died in Romania as part of the latter. He is assumed to be the trouvère (north French troubador poet-composer) recorded only as the "Vidame de Chartres", to whom eight songs have been attributed. Through his sister the title passed to the lords of Meslay-le-Vidame, Eure-et-Loir.
