La Luc is Clara and Theodore's father. He is the minister of the town of Savoy to which Adeline runs when La Motte helps her escape from the abbey. La Luc and his family take in Adeline and nurse her to health. After she is healthy, La Luc "adopts" Adeline and treats her as one of his own children. During Theodore's prison stay and his trial, La Luc's already poor health becomes worse and worse. After Theodore is pardoned, La Luc is able to travel to Montpelier, where his health is restored.
