Robert II de Pierrepont

Robert II de Pierrepont (died 1364) succeeded his father John V as Count of Roucy and Braine after Crécy in 1346. He was royal lieutenant in Vermandois and governor of Burgundy, and in 1356 ceded Braine to his younger brother Simon.

Captured at Poitiers in 1356, he paid a heavy ransom. In December 1358 the English took the castle of Roucy with him and his family inside; they were ransomed and the castle was retaken the following July. He died in 1364, leaving one daughter, Isabelle.
