HUGO [X] von Egisheim (-murdered Niedersasbach 5 Sep 1089). His parentage is confirmed by a charter dated 1091 which records the foundation of the monastery of Toul Saint-Léon and the part played by "Hugoni comiti filio comitis Henrici…et sua comitissa"[249]. Pibon Bishop of Toul granted privileges to the monastery of Toul Saint-Léon and recorded the donations made by "comes Hugo de Dasborc…Henrici filius…et nobilis prosapie beati Leonis…assensu coniugis suæ" by charter dated 1091[250]. Graf von Dachsburg. The Chronicon of Bernhold records that "Ugo comes de Eginisheim" was killed by a servant of the Bishop of Strasbourg "in cubiculo ipsius…II Non Sep" in 1089[251]. m MATHILDE de Mousson, daughter of LOUIS Comte de Mousson & his wife Sophie of Upper Lotharingia (-[28 Nov 1091/8 Mar 1105]). "Filia Wilelmi comitis de Burgundia Hermentrudis…" founded the Cluniac abbey of Froidefontaine by charter dated 8 Mar 1105 in which she names "suis antecessoribus…Lodewico, Sophia eius uxore, et filiis eorum Brunone, Theoderico, Lodewico, Friderico, filiabus vero Mathilde, Sophia, Beatrice…"[252]. She was present with her mother at the château de Bar 28 Nov 1091[253]. "Matthildis ancilla" (assumed to be Mathilde, daughter of Louis Comte de Mousson) confirmed donations to the abbey of Sainte-Croix, Wolfenheim, "ad Herlischesheim" donated by "comitissa Hiltegardis" for the soul of "filii sui Lodewici comitis", "ad Dambach" which "mater mea" donated for the soul of "patris mei", "ad Monstrol" which "dominus noster Hugo" donated, by undated charter which states that "domnus Hugo attavus meus" built the monastery[254]. She addressed a charter pre-1100 to the abbey of Sainte-Croix, Wolfenheim, in which she names her maternal grandmother[255]. Grosdidier de Matons reports a claim that Mathilde married secondly "Valéran Redon de la maison de Crépy-en-Valois"[256], which is based on a spurious document allegedly dated 20 Aug 1118 in which "Renauldz quenz de Bar et de Monceonz" confirmed an agreement whereby "ma ante madame Mahauz monsigneor Walranz Redon sun mari" received Fontenoy and Nanteuil-le-Haudoin under his wife's inheritance[257]. He highlights the apparent confusion with Clémence, great niece of Mathilde and daughter of Renaud I, who married Thiébaut de Crépy Seigneur de Nanteuil-le-Haudoin and speculates that the document in question was a 17th century copy of a spurious act which was fabricated in 1313 by Renaud de Bar Bishop of Metz to prove a property claim against the king of France
