[4] The qualificative of the former name -en-Ouche, means "in the Pays d'Ouche", a traditional region of Normandy, to make the difference with other Livets, like Livet-sur-Authou.

[10] Many de Livet family members were associated with the Knights Hospitallers, a medieval chivalric order founded to protect pilgrims to the Holy Land.

The family traditionally bore as their coat of arms three molettes d'or (gold) on a blue (azure) background.

[13] Another branch of the family settled at Arentot in Ourville (now Arantot, hamlet at Ourville-en-Caux).

[15] During the Norman Conquest of England, a branch of the de Livet family followed the de Ferrers (later the Earls of Derby) to England, along with the Curzons (Notre-Dame-de-Courson) and the Baskervilles (Basqueville, now Bacqueville-en-Caux), who were also under-tenants of the old Ferrieres fiefdom in Normandy.
