Earl of Carnarvon is a title that has been created three times in British history. The current holder is George Herbert, 8th Earl of Carnarvon. The town and county in Wales to which the title refers are historically spelled Caernarfon, having been Anglicised to Carnarvon or Caernarvon. The traditional Welsh spelling is itself a modified form of the original name of antiquity, Caer-yn-Arfon, meaning fortification opposite the island of Mona (now called Ynys Môn, or Anglesey in English).
