VERDUN SURNAME'S ORIGIN
Regarding Verdun of England and Ireland, the surname of Verdun was first found in Buckinghamshire where they were descended from
Bertram de Verdun, a Norman baronial name from Verdun, near Avranches in Normandy, where they were descended form the Counts of Verdun (speculative), and came to England in 1066 and was granted Farnham Royal in that shire. Tradition has it that on the day of the Coronation of William I, he provided a glove for the King's right hand. In 1095 he served as Sheriff of York. He also held lands in what is now known as Alveton or Alton in Staffordshire (https://www.houseofnames.com/de+verdun-family-crest).
In Normandy the name of Verdun appears for the first time in 1076 in a charter of Guillaume fitzWimund of Avranches, with Ernesius de Verdun, canon of the Cathedral St. Andrew of Avranches and Bertram de Verdun, of Farnham Royal.
