Henry Jenner suggested that Treworlas was named after Gorlois, the legendary duke of Cornwall, who he believed was a real fifth or sixth century figure, either a petty chief who was a vassal of the Royal House of Dumnonia, or – if the leaders of the Britons that had been displaced by the Saxons had become the kings of Dumnonia – Gorlois may have been of the line of the original chiefs of the Dumnonii that had been supplanted by the Britons.[2]
