He [Robert de Belleme] married before 9 September 1087, Agnes, 1st daughter and coheir of Guy I, COUNT OF PONTHIEU, by Ada. Agnes, who was sole heir to her father's comtÈ, was treated cruelly by her husband, who kept her shut up for a long time in his castle at BellÍme. She escaped by the help of a faithful chamberlain, took refuge with Adela Countess of Blois and retired to Ponthieu; whence she never returned to her husband. She was living on 6 October 1100, but died probably not very long afterwards. Robert died 8 May, not earlier than 1131, almost certainly in Wareham Castle and was presumably buried at Wareham.[f] [Complete Peerage XI:689-96, (transcribed by Dave Utzinger)]
