MATTHEW de Graville (-after 1172). Domesday Descendants says that Matthew was "presumably son of William [II] and Oliva de Tancarville, daughter of Rabel and Theophania de Richmond"[840].

The Liber Niger Scaccarii records the "carta Mathæi de Gerardivilla" among the certificates for knight-service in Hertfordshire in 1168[842]. "Mattheus de Gerardivilla" accounted for "iv mil. et ad suum servitium xii mil. et dim" in the Pays de Caux in 1172[843].

Stapleton suggests that the mother of Guillaume Malet de Graville was Olive de Tancarville, daughter of Rabel de Tancarville & his first wife Tiphaine de Penthièvre[845].

Matthew & his wife had children
