The Scottish surname Hervey, also found in England and Ireland, is derived  from the Breton personal name Aeruiu or Haerviu, composed of the elements haer meaning “battle or carnage” and  vy meaning “worthy,”which was brought to England and Scotland by Breton followers of William the Conqueror, for the most part in the Gallicized form Hervé. The first written reference to the name was in 1190 when William Hervi, was recordedin the 'Calendar of Abbot Samson of Bury St. Edmunds, Suffolk.' Bagenal Harvey was one of the 1798 leaders of the Irish rebellion, whilst curiously Robert Hervie of Scotland was a member of the Huntly Volunteer force, raised to combat a possible French-Irish invasion.
