For English set how about just capture a city in France instead of NE France?
Also why Liberalism for Germany? I thought the "first civ to discover" it was France.
For English Control all areas of the commonwealth should be in "colonization" set, replaced by maybe "conquer or vassalize America by X-AD". In the new colonization set add the commonwealth thing, also be the first civ to have a size 7-10? city in NAm, and maybe first civ to adopt commonwealth? If not then first civ to research a certain tech I guess.
