'Baron Dynham (alias Dinham and Dinan) is a title which has been used twice in the English peerage, for: * Oliver de Dynham, 1st Baron Dynham (c.1234-1299), of Hartland and Nutwell in Devon and feudal baron of Cardinham in Cornwall. He was summoned by writ of King Edward I to attend parliaments from 24 June 1295 to 26 August 1296, the writs being addressed to Olivero de Dynham or Dynaunt, by which he is held to have become Baron Dynham. The barony was not apparently hereditary, as determined in 1914 by the House of Lords Committee for Privileges concerning a claim to it made by Viscount Gage and Sir Robert Bourchier Sherard Wrey, Baronet . No writ of summons was ever issued to his descendants for five generations until 1467, when a new peerage was created. * John Dynham, 1st Baron Dynham
