I understand that the effective unification of England is represented by William's coronation and the chart for 25th December 1066. The charts for the Acts of Union in 1707 and 1801 are used for the UK. As the former represents the union of England with Scotland, and the latter the union of Britain with Ireland, has anyone ever used a chart for the Anglo-Irish Treaty that took effect on 6th December 1922 that presumably best fits the present title of "United Kingdom of Great Britain and Northern Ireland"? If so, what time is taken? If not, why not please?

If so, what time is taken?

This is discussed on a previous thread:

If not, why not please?

I guess opinions differ as to how "effective" unification has actually been

Myself, I wonder why whenever we discuss something like this, the Channel Islands fall off the map. As crown dependencies, do people use the 1066 chart? I suppose that makes sense. Sorry for going off point, but it bothers me somehow.
