Adèle de Batz de Trenquelléon was a French religious sister born in 1789 who co-founded the Marianist Sisters alongside William Joseph Chaminade. Although she initially aspired to join the Carmelites, she dedicated her life to serving the impoverished and educating children. Following the French Revolution, her family experienced exile in Spain and Portugal before returning to France. She eventually established a religious community designed to support missionary work and provide care for those in need, blending her spiritual inspirations with practical service to the poor.
