BEATRIX de Vermandois ([880/83]-after 26 Mar 931). None of the sources so far consulted state explicitly that Heribert [II] and his sister Beatrix were the children of Heribert [I] but this looks probable. Her birth date range is estimated from her eldest daughter giving birth to her own first child in [915]. The Historia Francorum Senonensis records that "sororem Herberti" was the wife of "Robertus princeps" who rebelled against Charles III "le Simple" King of the West Franks[1620]. Guillaume de Jumièges records that Duke Robert's wife was the sister of Héribert, and that the couple had a son named Hugues[1621]. The marriage may have been arranged to confirm her father's reconciliation with Eudes King of France, who was her husband's uncle[1622]. Werner suggests [897] as the date of the marriage, on the assumption that it followed the political reconciliation between Béatrix's father and Robert's uncle[1623]. As discussed in relation to Robert's first marriage in the document FRANCE CAPETIAN KINGS, there is a possibility that Robert's first wife was still alive in 907, which would of course mean that Béatrix's marriage took place after that date. m ([897]) as his second wife, ROBERT Marquis en Neustrie, son of ROBERT "le Fort" Marquis en Neustrie & his [second] wife --- ([860]-killed in battle near Soissons 15 Jun 923). Comte de Paris 898. He was elected 22 Jun 922 as ROBERT I King of France.
