Hugh de Montgomerie, Count of Montgomery, married Josseline, the daughterof Tourode and his wife, Neva Duceline de Crepon. Josseline was theyoungest sister of Humphros de Velutes, and he was the father of Roger deBeaumont or Bellomont, father of Robert de Bellomont, who married Isabelde Vermandois, daughter of Hugh Magnus, crusader. This shows theconnection of the Montgomeries with the most noted families. Hugh andJosseline had four sons: Roger, Robert, William and Gilbert. This lastson, Gilbert, was undesignedly killed by his brother Roger's wife Mabelin 1064. In her hatred for the family of Giroie she had designed to makeaway with Ernauld, son of William Giroie. She invited him, on his returnfrom Poland, to pay her husband a visit and prepared for him poisonedmeat and drink. The design was discovered to him in time and on arrivingat her house he declined partaking of any refreshment. But Gilbert, whoaccompanied Ernauld, ignorant of Mabel's plans, took unhesitatingly thecup and drank the wine and died within three days. Vicomte de laHiesmois. The Complete Peerage vol.XI,p.682-683.
