You're doing well, Allan. There are only two memorable dates in English history. The source of that info may be the 'most memorable English history' that Ian is referring to.

History was never a strong subject of mine (or, if you prefer, history was the equal of many of my subjects ;-( ). I reckon I know maybe half of the answers. That means I probably really know about two or three of them.

To make a start, then. No 3. Catherine was married (or just betrothed?) to Henry's elder brother, and to marry your brother's wife (after he dies, naturally!) is forbidden in the Old testament - (a guess here) Leviticus. He was given a papal dispensation to allow the marriage to take place.
