Well, Martin didn’t really stretch his brain too hard when he named them “Stark” and “Lannister”.
It is interesting how he took lots of real historical events and places and just exaggerated them, like the Wall being Hadrian’s Wall, and the Red Wedding being based on the “Black Dinner”.
I think Daenarys is Henry Tudor. He was referred to as “the dragon” and that was his battle standard.
Stark and Lannister are based on real character? What are the real names?
