I would like to detach one of them with the correct son whose name was also Robert II d’Estoutevillle but he was married to Blanche de Rieux who was the daughter of de Guesnoc, seigneur de Rieux ).
Robert II, was Lord Estouteville and Valmont, did defend the Duke of Normandy against Henry 1st of England.
He did have a second marriage to "Adélaïde (Aélis) de Beaumont"
He did have grandchildren that ended up in England. Maybe the generations were mixed up ?
[[CLOSED]] Solution found by detaching grandson "as a son" .
