Queen Isabella, who was married four times and had at least 5 surviving daughters, instead has several sons who survive her. If she had a son by her second husband, Conrad of Montferrat, he would have eventually succeeded to the throne of Jerusalem. What about the other sons? Assuming there is at least one by each of her other 2 husbands, Henry of Champagne and Amalric of Lusignan, what if any territories do they inherit? Amalric's son by his first wife became king of Cyprus. I don't know what if any provisions were made for the children he had by Isabella. I'm sure a surviving son would have really complicated things. Any thoughts?
