Richard le Goz, Viscount of Avranches - Richard le Goz & Emma de Conteville have too many children

According to the profile overview and FMG Medlands, this couple should have 4 children:
Hugues d'Avranches 'Lupus'
Marguerite, married Ranulf Vicomte du Bessin
Helisende, married Guillaume [II] Comte d'Eu
Judith, married Richer de Laigle

However there are very many more than these attached as children in their tree. I am proposing detaching these children if I recieve no substantiated objections.
