Lol Neal if you are going to try to keep track of who was who in the noble/royal families and what they were doing and why during that period of English history, you need a LOT of cheat sheets. Used to be a bit of an obsession of mine and I had multiple family trees drawn up and tucked into all my books, it was the only way to stay sane.
At some point they should have passed a law about not using the same damn name more than once during, say, a three-generation period in any one family.
Aaaaaand every time someone says "Plantagenet" I want to watch
The Lion in Winter again, as if anyone needs an excuse to do that.
