Cockayne states that Hugh d'Avranches was the son of Richard le Goz, Vicomte d'Avranches and that his mother was Emma de Contville. 
Cawley observes that a manuscript relating to St Werburgh’s Chester records that “Hugo Lupus filius ducis Britanniæ et nepos Gulielmi magni ex sorore” transformed the foundation into a monastery and states that this suggests that the mother of Hugues may have been a uterine sister of King William, and therefore daughter of Herluin de Conteville. However, no indication has been in other primary sources which supports the contention that Hugues was the son of a duke of Brittany. It is assumed therefore that both lines of his parentage have been romanticised in this document to improve his status and reputation. 
Reflecting this more recent thinking, C. P. Lewis, writing in the Oxford Dictionary of National Biography, refers to Hugh's mother as "an unknown mother formerly identified on the basis of unsatisfactory evidence as Emma, supposedly a half-sister of William the Conqueror. 
Based on this, the link to Emma Conteville as the mother of Hugh d'Avranches has been disconnected.
Not listed by Cawley (2006) or Wikipedia as a daughter of these parents.
