Raynald of Châtillon
From 1180, Sibylla held Jaffa and Ascalon with Guy, and had four daughters with him. Their marriage divided the nobility into a faction supporting Guy (Sibylla; the king; their mother, Agnes; their stepfather the lord of Sidon, Raynald; their maternal uncle, Joscelin of Courtenay; and the lord of Oultrejordain, Raynald of Châtillon) and a faction opposing him (Sibylla's paternal kinsmen Bohemond of Antioch and Raymond of Tripoli; Baldwin and Balian of Ibelin; and her stepmother, Maria Komnene). In order to prevent the opposing party from setting up a rival claimant, the king took his mother's advice and, in October 1180, betrothed his half-sister Isabella, Maria's daughter and Balian's stepdaughter, to Humphrey IV of Toron, stepson of Raynald of Châtillon. From March 1181, both Sibylla and Guy were associated with King Baldwin in public acts.
