[ECHA311] Giroie/Geroius/Gerve (born c.968), Seigneur d'Echauffour & de Montreuil, said by Guillaume Jumieges to issue from two noble families of the Franks and the Bretons. He was betrothed to a daughter of Heugon, whose dowry would have been the castles of Montreuil and Echauffour, but she died before the marriage could take place, after which he may have lost his Seigneur titles. He married instead [MONB312] Gisla/Gisela (daughter of Thurstan de Bastembourg aka Thurstain de Montfort, see MONTFORT-SUR-RISLE), by whom he had seven sons and four daughters, in order:

"Ernauld, Foulques qui périt avec le comte Gilbert, Guillaume, Raoul Male-Couronne, Robert, Hugues et Giroie et les filles Heremburge, Emma, Adelaide et Hadvise".

Orderic Vitalis also names Giroie and his eleven children. Together with his grandsons Robert and Hughes de Grantmesnil, Giroie founded the monastery of Saint-Evroul (1050).
