Yes, that's my understanding. The United Kingdom of Great Britain was formed by the Acts of Union of 1707, but Ireland was kept subordinate. After the Act of Union with Ireland in 1800, the combined kingdom was the United Kingdom of Great Britain and Ireland. And then of course most of the Irish buggered off in 1922, leaving the United Kingdom of Great Britain and Northern Ireland. I have argued at work that JOLF UK should actually call itself JOLF GB since the Belfast office is actually part of the Irish firm. Nobody agreed with me.
There was never an equivalent 'Act of Union' (i.e. passed in both parliaments) with Wales since Wales was simply conquered by England. Welsh law still applied for some time after the conquest until Henry VIII formally annexed Wales. Someone who was Welsh was (at least constitutionally) English since Wales was part of England. This was clarified by the Wales and berwick Act of 1746 which made it clear that 'England' included Wales (and also Berwick-upon-Tweed). The constitutional status of Wales has been muddied by recent developments like the Welsh Assembly.
