Balian of Ibelin
Isabella's stepfather, Balian of Ibelin, was one of Conrad's supporters. He and his partisans decided that the marriage of Isabella and Humphrey should be annulled. The marriage was childless. The contemporaneous "Itinerarium Regis Ricardi" describes Humphrey, around 1190, as "more like a woman than a man, gentle in his dealings and with a bad stammer". Isabella's mother, Maria Comnena, entered Isabella's tent, and forced her to leave her husband.
