after watching 'elizabeth' and ' the other boleyn girl' i have become very interested in the line of succession and how we got to today with queen elizabeth on the throne. however, i find it hard to get a clear picture in my head of who was related to who and why X took the throne when Y didn't. i would like to be able to draw out a diagram of this, like a family tree, showing all the people involved say from the tudors onwards.
are there any books that would help me understand all of this? i am from northern ireland so my experience of history in school will have been different to what was taught in england, scotland or wales.
