a) GUILLAUME [II] de Grantmesnil (-[3 Oct], 1118 or after). Orderic Vitalis names “Guillelmum et Rodbertum” as the two sons of Guillaume de Grantmesnil and his wife[381]. He succeeded his father but did not long survive him[382]. "La contessa Mabilia, vedova del protosebasta Guglielmo di Grantmesnil ed il figlio Guglielmo" donated the church of San Pietro di Bragalla to Cava by charter dated Sep 1117[383]. The possibility of his death “3 Oct” is discussed under his possible wife Agatha.
