m ERMENTRUDE, daughter of GODEFROI Comte de Verdun & his wife Mechtild of Saxony ([965/80]-7 Mar after 1010). The primary source which confirms her parentage and marriage has not yet been identified. Roland records the wife of Arnaud as “Ermentrude, fille de Godefroid le Captif et de Mathilde de Saxe” but he does not cite the corresponding primary source[284]. He states also that “Arnoul seigneur de Florennes reçut en bénéfice du comte Herman son beau-frère l’abbaye d’Hautmont”, again without citing the corresponding primary source but Roland’s wording suggests that the document may indicate the family relationship between the two parties[285].
