It is the United Kingdom of Great Britain (England, Scotland, Wales) and Northern Ireland.
Northumbria, however, does not exist anymore, its now a bunch of English counties, and the southern half of Scotland (south of the Firth of Forth).
Without more details on which part of Northumbria is meant it's impossible to know if Enlgand should be included, it may also be wrong to include England if its only a small part and its most / all of Scotland, Wales, and Northen Ireland
The author may be getting confused with the similarly named modern county of Northumberland. You'd be surprised how often the border region between England and Scotland is confused, misplaced, or forgotten about.

Edited for clarity
I thought it odd to include Northumbria in one list, but leave it (or England) off the other. But then including a historic county along with countries is odd anyway. I assumed they meant northern England because the parts within Scotland wouldn’t need to be called out again within a list.
It gets even more perplexing when you consider someone like .. well, me .. who would say "I'm from X, but not of X".
