LOL @ "completely wrong"
Firstly, there are two acts of Union and in any case it's the union of the crowns (not an act of either parliament) which originally 'united' Scotland and England, under our king, James VI who became James of England, as well. James attempted to foster a new unity under the name "Great Britain" (where that phrase dates to, essentially, in terms of UK history) but failed as did several attempts in the Scots and English parliaments to create a political union.
In 1707, after a lot of work the previous year, the Acts of Union were passed in the Scots and English parliaments, despite strong opposition in both nations. In an effort to further underline this supposed new entity it became the fashion of Unionists to refer to Scotland as "North Britain" and on the heels of that came various attempts to suppress Scots identity, especially that of the Gaels (Highlanders and Islanders). This new entity was styled "The United Kingdom of Great Britain", incorporating essentially we today call "Norther Ireland" or Ulster (most of which had been settled by Scots) and also Wales which was subject to the English crown. Later, in 1800, all of Ireland was joined to this union, forming the United Kingdom of Great Britain and Ireland. When the Irish successfully won independence, this styling was retained even though territorially what was left amounted to the previous UK of GB, thus we are today "The United Kingdom of Great Britain and Northern Ireland". HTH
P.S. Wales is and has been a principality or princedom subject to the English crown ever since its final conquest by Edward; it's never stopped being Wales.
