EMMA . She must be one of the three unnamed daughters referred to by Orderic Vitalis. She is named as the sister of Judith d'Evreux by Orderic Vitalis, who specifies that she married "another count whose name I cannot recall". In another passage, the same source specifies that their mother had only one daughter by her second marriage. It must be concluded that Emma was one of their mother's daughters by her first marriage. She fled Normandy with her [half] sister Judith.
