Sohier, Count of Enghien
Sohier of Enghien (1324–1364), son of Walter III of Enghien and Isabella of Brienne, became lord of Enghien in 1345. When his mother divided the inheritance of her brother Walter VI of Brienne, he received the counties of Brienne and Conversano and the titular duchy of Athens, and succeeded Walter as constable of France.
Captured amid the feuds of Hainaut, he was beheaded without trial at Le Quesnoy on 21 March 1364 on the orders of Albert of Bavaria.
