Oh, any number of things could fit here. You could name him Mohammed or Saladin. Fidel maybe. A good friend of mine named himself Gustav.
Really, though, any name can be heroic after a hero uses it. John, Mark, Matthew, Jesus, Mohammed, Abraham, etc were probably not very common names of their time before someone with each of those names became immensely popular. Now they are some of the most used names in humanity. So, why be an reference to anything? I don't know any hero in history named Andreas. Name yourself that and, through your heroism, make naming one's kid Andreas as fashionable on Earth as James or Michael is now.
