I was 'offered' a merge which involved two sets of parents - using Hugues' declared birthdate ( 890 ) as a reference I opted to remove the alternative Parents: Malahulc / Haldrick Eysteinsson (845 - 912) & Maud et Temois de Boulogne et Ternois (895 - 964) on the grounds that Maud, the proposed mother, wasn't born until 895.
Clearly any refinement of Hugues birthdate may invalidate this logic.
