Sevenoaks, a town in England Kent, and Sevenstreams. Both are associated with local rebellions and dissatisfaction from the ruling dynasty as in the case of the BWB and the real word rebels that were lead by Jack Cade. Thing is that no one really knew who Jack Cade was, and was possibly a fake identity, and he also may have taken the name John Mortimer. It kind mirrors Beric's story, with some not knowing if he is truly alive or when the BWB members start mocking that Frey when each claim each other to be Beric. What convinces me that there is a parallel though is that Jack Cade's rebellion started in a very controlled manner. He actually marched on London with the intent of doing good and ridding the Kingdom of what were considered corrupt individuals in power while improving the lives of the commoners. Thing is that when he entered London he lost control of his men and they started looting, and his men were quickly expelled when the citizens turned against them. In the books we see the deterioration of the BWB from their more noble actions to becoming just another outlaw band. It makes a better comparison than Robin Hood in my opinion.
