List of monarchs in the British Isles

List of monarchs in the British Isles:

Willy Willy Harry Steve,
Henry Dick John Henry three;
Then three Edwards Richard two,
Henry Four, Five Six then who?
Edward four five, Dick the bad,
Two more Henries, Ned the lad;
Bloody Mary she came next,
Then we have our Good Queen Bess.
From Scotland we got James the Vain;
Charlie one, two, James again.
William and Mary, Anna Gloria,
Four Georges, William, and Victoria.
Edward, George, the same again,
Now Elizabeth - and the end.

Sure this'll come in useful at some stage.
