Hey guys

I have just finished watching episode 3 of The Tudors.  In this one Henry, Katherine and Mary are on progress to the north to York.  On the way they visit many places, among them Henry mentions Lincoln & Boston.  Now I know for a fact that they visited Lincoln, but he mentioned Boston. 

I live in Boston and have never heard that he vistied here or cannot find anything on the internet.  Does anyone know if this is true or something that the writers of The Tudors made up?
