DUNDAGELL: Hals, citing Carew's Survey of Cornwall, says, "Dundagell (alias Dyndagell, alias Bosithney) gave name and original to an old family of gentlemen surnamed De Dundagell, now extinct, of which family was Robert de Dundagell, who, temp. Rich. I., held in this county, by the tenure of knight service, five knight's fees." He says also that the name Dundagell means safe, secure, or impregnable fort or fortress; and Dyndagell safe, secure, impregnable, or invincible man; or a man so fortified, magnified, or fenced by art or nature that he was not liable to hurt or danger, referring perhaps to the King or Earl of Cornwall, whose fort or castle it was"! In Domesday, 20 Wm. I. (1087), this place was taxed under the name of Dune-cheine. Tonkin says "tin is the same as din, dinas, dixeth, deceit; so that Tindixeth, turned for the easier pronunciation to Tintagel, Dindagel, or Daundagel, signifies the Castle of Deceit, which name might be aptly given to it from the famous deceit practised here by Uter Pendragon, by the help of Merlin's enchantment." Pryce renders "Tintagell (now Tintagel), the modern name of Dundagell, Dundagel, the castle of deceit (tin, din, a fortified place or castle)."
