William of Tyre names "Walterius de Sancto Valerius Bernardusque filius eius" among those present at the capture of Nikaia in 1097. Orderic Vitalis also names him as son of Gauthier, with whom he was present at the capture of Nikaia in 1097. Murray suggests that Gauthier de Saint-Valéry and his son Bernard were the same persons who are named by Albert of Aix as "…Walterus de Domedart et eius filius Bernardus…" among those who took part in the siege of Nikaia, suggesting that "Domedart" indicates a toponym derived from the saint’s name "domnus Medardus" and that it could indicate Domart-en-Ponthieu. Domesday Descendants records that "Bernard de Saint-Valéry and Dommard and Matilda comitissa" donated property to Berteaucourt. The primary source which confirms that he was the same person as the Bernard de Saint-Valéry named by William of Tyre and Orderic Vitalis has not yet been identified.
Domesday Descendants records that "Bernard de Saint-Valéry and Dommard and Matilda comitissa" donated property to Berteaucourt. It is likely that Mathilde retained her title "comitissa" after the death of a first husband who was comte, although the primary source which confirms that this is correct has not yet been identified. 1
