The Dupré family lived in the Ile de France region from at least the eighteenth century. Little is known about Julien Dupré’s great grandparents, but his grandfather, Pierre Paul Balthazar Dupré (ca. 1788-1851) was recorded as the buyer of a house in the village of Villemomble about ten miles east of Paris in 1832. He and his wife, Jeanne Cécile Grignon (ca. 1788-?), settled in the center of the village at Grande rue 17. At the time of this purchase, their son, Jean-Marie-Pierre Dupré, was twenty-three years old.
The house no longer exists, but it was reportedly a three-story structure with a small courtyard and a garden. Georges Laugée, Julien Dupré’s brother-in-law, later painted a small oil sketch of the garden.

1834: Julien Dupré’s father, Jean-Marie-Pierre Dupré, was born on February 8, 1809 in the 3rd arrondissement of Paris; he was baptized at the Church of Saint Eustache on November 12, 1809. At that time, the Dupré family lived at the Galerie des Innocents, no. 1. As a young man, he worked as a jeweler, as did a number of other family members. On February 13, 1834, he married Irma Marie Madeleine Françoise Bouillié at the Church of Saint-Merri, a sixteenth-century gothic church in the Marais district of Paris.
 In French, there are two nouns for the word “jeweler”. One is bijoutier/ière which refers to what would be described as costume jewelry in English. The other is joaillier/ière which refers to fine art jewelry. Jean-Marie-Pierre Dupré most likely began his career as a bijoutier and then evolved into a joaillier. His eldest son Jean and his daughter Julie both became joaillier/ière. Julien Dupré’s cousin, nephew and son-in-law were also jewelers.
