The surname Debonville was first found in Normandy (French: Normandie), the former Duchy of Normandy, where the family has been a prominent family for centuries. The Itineraire de la Normandie records three places so called-two near Rouen and the third near Yvetot. The family were well established in the region of Calvados. They held the Castle of Bonneville or Bondeville in Normandy.
