GISELE de Vaudémont (-26 Dec after 1141, bur Saint-Mihiel). The Chronicle of Alberic de Trois-Fontaines names "comitem Wanderii Montis Hugonem et sororem eius Gislam" as children of "Gerardum…primus comes Wanderi Montis" & his [second] wife, specifying that Gisela was "comitissa Barri"[803]. Her first marriage is deduced from the same source which records that "comes Raynaldus Barri" became the stepfather of "comitis Frederici Tullensis et fratrum suorum Theoderici et Wedrici" although without naming his wife[804]. It should be noted that these two texts do not establish beyond doubt that the widow of Renier Comte de Toul was also the daughter of Gérard Comte de Vaudémont. It is therefore not impossible that Comte Renaud married twice, firstly to Gisèle daughter of Comte Gérard, and secondly to the unnamed widow of Comte Renier. However, no indication has yet been found in the primary sources to indicate that this is correct. m firstly RAINARD [III] Comte de Toul, son of FREDERIC [I] Comte d'Astenois et de Toul & his wife Gertrude de Toul (-[1116/20]). m secondly ([1120]) as his second wife, RENAUD I Comte de Bar et de Mousson, son of THIERRY de Mousson & his wife Ermentrude de Bourgogne [Comté] ([1175/77]-on ship in the Mediterranean 10 Mar 1149).
