This stamp depicts the arms of the de Bailly and the Tréton de Vaujuas-Langan families. It is difficult to identify the exact owner of a stamp, especially when variations in the coat of arms occured over the generations. The de Bailly arms have not changed, but the Tréton de Vaujuas-Langan arms on this stamp appear with a cinquefoil (five-petaled flower) instead of a wheel. I believe that this stamp belonged to Aimée Pierrette Charlotte de Bailly, the daughter of Charles Gaspard, Marquis of Fresnay. She and her husband probably adopted the cinquefoil instead of the wheel as a mark of cadency. Aimée Pierrette was the wife of Louis, Marquis of Vaujuas-Langan. Louis was the son of Jacques Tréton de Vaujuas and Émilie de Langan du Boisfévrier, whose arms were Sable and charged with a lion. While Louis adopted a quartered coat of arms combining the arms of his parents, Aimée Pierrette Charlotte chose to display the arms of her husband's paternal lineage only.
