Ide de Boulogne was born circa 1055 to Eustache II de Boulogne (c1017-1087) and Ide de Verdun (c1040-1113) and died circa 1102 of unspecified causes. She married Herman van Malsen (c1030-aft1080) 1068 JL . She married Conon de Montaigu (?-1106) .
Ide's second husband had four sons. The two eldest sons were commanders in the First Crusade in 1098, and therefore probably stem from Conon's first marriage. Conon's youngest sons, both priests, may have been Ide's.
