Answer: There is nothing in the film to suggest anything other than that they are brothers. Paul sells out his family, takes the money and goes away. It is only natural that they would not want to speak of him later on. Daniel on the other hand, keeps a certain track on Paul, especially since he also got into the oil business and became a minor competitor to Daniel.
