This is my Burgundy->Lotharingia game, on year 1423. I had free cores on the Benelux region after conquering the provinces there. I then had a deadly war (for about 4 years, I think) with France, and only got three provinces out of it, which was worth it. I became conquering German minors to form Lotharingia, and was successful forming the nation. I now have cores on Savoy, Southeastern France, and northernwestern German minors.
I inherited Scotland around 1416 and have a PU with Castille and Provence since 1412 and 1413, respectively.
