The name of Lovett as differently written in Domesday is Loueth, Lueth, DeLuveit, Deluvet, Lovet or Lovett Burke's Landed Gentry
The family of Lovett is of Norman extraction and can be authentically deduced from Richard DeLouet, living at the time of the Conquest. His son William married Engaine. The Conqueror appointed him Master of the Wolf hounds. Burke's Landed Gentry
There is a tradition that an early ancestor of the family was Master of the wolf hounds to one of the Norman kings. This probably arose from the peculiar Arms of the family. Quarterly the wolves heads, and three wolves heads passant and the crest a wolf's head.
These bearings are of course of the allusive kind and relate to the name which is a softened derivative of the French loup, louve a wolf. Patronomic Brittanica
