 Otto de Grandson

Otto de Grandson (c. 1238–1328), sometimes numbered Otto I to distinguish him from later members of his family with the same name, was the most prominent of the Savoyard knights in the service of King Edward I of England, to whom he was the closest personal friend and many of whose interests he shared.The son of Pierre, lord of Grandson near Lausanne, the young Otto travelled to England probably in the company of Peter II of Savoy in 1252, certainly not later than 1265.
