Vernon is a surname, from a masculine name that is derived from the Gallic word vern for Alder tree (also springlike, flourishing, or full of life) and a Gaulish-Latin suffix indicating a location.
Vernon was introduced into England as an aristocratic surname at the time of the Norman conquest.
[1] A few years later Hugh was recorded as one of the men consenting to a grant of land by Duke Robert of Normandy to the abbey of St Wandrille at Serville, ten miles north of Rouen.
In that year Duke William, Robert's son, then granted the title to his cousin, Guy de Burgundy.
Hugh survived until the early 1050s when he was succeeded as lord of Vernon by his son William.
