MATHILDE (-[28 Nov 1091/8 Mar 1105]).

• Father: LOUIS, son of RICHWIN Comte de Charpeigne
• Mother: Sophie of Upper Lotharingia. MATHILDE (-[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…"[54]. She was present with her mother at the château de Bar 28 Nov 1091[55]. "Matthildis ancilla ancillarum Christi" (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[56]. Viellard dates this charter to [1090][57]. Grosdidier de Matons reports a claim that Mathilde married secondly "Valéran Redon de la maison de Crépy-en-Valois"[58], 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[59]. 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[60]. m HUGO [X] Graf von Dagsburg, son of HEINRICH [I] Graf von Egisheim und Dagsburg & his wife --- (-murdered Strasbourg 5 Sep 1089).
