Per MedLands, Jean de Valois & Guillaume III de Hainaut didn't have a daughter named Catherine d'Avesnes de Hainault (Jeanne de Valois, Comtesse de Hainault). The first time I saw it here on Geni I was surprised, since in all my reading about Katherine de Roet, only her father was named and even his proper name isn't a certainty, mother was unknown. Curators really should be sure of an entire line - even if only their own - before signing off on Master Profiles.
