 It is a sign of Edward 's high regard for Lancaster that he would bestow such extensive privileges on him . The two men were second cousins through their great @-@ grandfather Henry III and practically <unk> ( Edward was born in <unk> ) , so it is natural to assume that a strong sense of <unk> existed between them . Another factor that might have influenced the king 's decision was the fact that Henry had no male heir , so the grant was made for the Earl 's lifetime only , and not intended to be hereditary .
