  Chapter 13. SEIGNEURS de JOINVILLE
  Etienne, earliest known ancestor of the Seigneurs de Joinville {Haute-Marne}, is recorded in the early 11th century. According to the Chronicle of Alberic de Trois-Fontaines, he was from Vaux, near the abbey of Saint-Urbain[1155], the village of Vaux-sur-Saint-Urbain being located about six kilometres south of Joinville, adjacent to Saint-Urbain Maconcourt, near the Marne river. His parentage is unknown. Alberic de Trois-Fontaines also records that Etienne started building the first castle of Joinville with the help of his father-in-law and that he was "comes Ioviniaci"[1156], although no other sources have been found which corroborate that he bore this title. It is possible that the reference results from confusion between the names "Joinville" and "Joigny" {Yonne}, the latter being located south-west of Troyes near Auxerre. Contemporary charters refer to Etienne's castle by the names "novum castellum" and "Junci-villa" (see below).
