Fortune of the Rougons

We enter the world of a fictional town of Plassans in Zola's native region of Provence and we are introduced to the eccentric heroine Adelaide Fouque, later known as Tante Dide, who becomes the common ancestor for both the Rougon and Macquart families. Her legitimate son from her short marriage to her late husband, a labourer named Rougon who worked on Dide's land, is forced to grow up alongside two illegitimate children.
