Bouchard de Marly

His father had participated in the Fourth Crusade and, unlike the French contingent led by Simon IV of Montford, had ventured as far as Constantinople, where he died shortly after the sack of the city on 27 August 1204.

Bouchard de Marly in 1204 sponsored the foundation of the abbey of Port-Royal des Champs.

In 1209, he participated in the Albigensian Crusade, where he joined Simon of Montford who was married to Alix de Montmorency, one of his cousins.

Simon laid siege to Lastours in the spring of 1211, and Pierre-Roger de Cabaret released Bouchard as an emissary presenting his terms of surrender.

Bouchard used the coat of arms of the lords of Montmorency, or a cross gules, quarterly four eagles (alerions?)
