Career
In 1335 King Edward III accorded him confirmation of the de Marny family charter, dating back to 1266. De Marny was the son of Sir William de Marney and Catherine Venables. De Marny fought in the Battle of Poitiers or Poictiers (1356) in which the English defeated the French.
He is best remembered now from William Morris"s fictional poem "The Haystack in the Floods," which imagines his death in a skirmish while attempting to reach English-held Gascony.
