ベーラ3世
Whether the father of Constance's second son, Baldwin, was Raymond of Poitiers or Raynald of Châtillon cannot be determined with certainty. Baldwin died fighting at the head of a Byzantine cavalry regiment in the Battle of Myriokephalon on September17, 1176. It is certain that Raynald fathered Agnes, who became the wife of Béla III of Hungary. Raynald and Constance's second daughter, Alice, became the third wife of Azzo VI of Este in 1204.
