Baldwin II of Jerusalem
Barisan's origins are obscure. The Ibelins later claimed to be descended from the viscounts of Chartres, but according to Peter W. Edbury, Barisan was probably from northern Italy. According to Jonathan Riley-Smith, however, he may have indeed been connected to Chartres, as the brother of Hugh of Le Puiset, Count of Jaffa; he would then have also been a cousin to the Montlhéry family of King Baldwin II of Jerusalem.
