Hugh de Montgomerie, Count of Montgomery, married Josseline, the daughter of Tourode and his wife, Neva Duceline de Crepon. Josseline was the youngest sister of Humphros de Velutes, and he was the father of Roger de Beaumont or Bellomont, father of Robert de Bellomont, who married Isabel de Vermandois, daughter of Hugh Magnus, crusader. This shows the connection of the Montgomeries with the most noted families. Hugh and Josseline had four sons: Roger, Robert, William and Gilbert. This last son, Gilbert, was undesignedly killed by his brother Roger's wife Mabel in 1064. In her hatred for the family of Giroie she had designed to make away with Ernauld, son of William Giroie. She invited him, on his return from Poland, to pay her husband a visit and prepared for him poisoned meat and drink. The design was discovered to him in time and on arriving at her house he declined partaking of any refreshment. But Gilbert, who accompanied Ernauld, ignorant of Mabel's plans, took unhesitatingly the cup and drank the wine and died within three days. Vicomte de la Hiesmois.
