m (Apulia 1100) SIBYLLE de Conversano, daughter of GODEFROI Comte de Conversano e Brindisi & his wife Sichelgaita --- (-Rouen [Feb/Mar] or [21 Mar] 1103, bur Caen or Rouen Cathedral).  She is named by Orderic Vitalis, who also names her father and says that he was the nephew of Robert "Guiscard"[268].  Guillaume de Jumièges records that Robert married "Sibylle sœur de Guillaume comte de Conversano"[269].  William of Malmesbury records that her husband married her on his return from Palestine, and that he was given an "immense sum" by way of dowry which he "lavished so profusely that in a few days he was penniless"[270].  Orderic Vitalis records that she was poisoned and died "in Lent"[271].  According to William of Malmesbury, she died "by disease"[272].  Orderic Vitalis alleges that Agnes de Ribemont, wife of Walter Giffard Earl of Buckingham, fell in love with Duke Robert, and states that the latter's wife was poisoned soon after although he does not directly attribute blame for her murder[273].  The necrology of Saint-Nicaise de Meulan records the death "XII Kal Apr" of "Sibilla comitissa Normannie"[274], although if this refers to Sibylle de Conversano it is not clear why she was not called "ducissa".  It is unlikely that the entry refers to Robert's daughter-in-law Sibylle d'Anjou as she was Ctss of Flanders when she died.
