There is Royal Prussia called Danzig-Pommerania too and Ducal Prussia with Konigsberg. The first was Polish territory since 10th cen., the later belonged to orginal Prussians. Teutons conquered the latter in 1242-1283 and the area germanized eventually. The turning point is 1525 when last rebellion of Prussians occured. After that date Ducal Prussia may be considered German.
Royal Prussia (the name was introduced to differ from Ducal Prussia after 1525) was almost always inhabited by vast majority of Poles. Germans were very rare outside cities and were outnumbered in the rural area even by Dutch who settled in very fertile delta of Vistula in 16th cen.
Problem with Danzig is that both Poland and Prussia (not Teutons) should get all income/no problem with it. But it is very hard to achieve.
Many thanks for the info
Yes, i see the problem to make a correct representation of these provinces. Indeed Ducal Prussia is baltic if i don´t recall wrong.
