I'm asking this because the highest-level administrative divisions are often named after their corresponding historical regions.
In Poland, it sometimes causes some controversies.
The most infamous example is the Silesian Voivodeship, which is only 48% Upper Silesian. It also contains 45% of Lesser Poland and 7% of Sieradz and Wieluń Lands. This leads to some outsiders calling cities like Częstochowa, Sosnowiec, or Żywiec "Silesian" much to the annoyance of their inhabitants, while they are historically located in Western Lesser Poland.
Some activists petition to change the voivodeship's name to "Silesian-Lesser Polish". However, this would discriminate the lands of Sieradz and Wieluń which are neither. So, perhaps naming it "województwo katowickie" after its capital, Katowice, would be the most neutral?
Ironically, these activists use the Warmian–Masurian Voivodeship as an example that you can include names of both historical regions in a province's name, but it turns out that this name also ignores the land of Bartia (also Bartenland or Barthonia). Not to mention that it also includes parts of Powiśle, Pomesania, and Mazovia.
Then, there are some quirky cases like Lubusz Voivodeship being named after the city of Lebus located on the other side of the Polish-German border, while one of its two capitals, Zielona Góra is at the western border of the whole of Silesia. There's also Holy Cross Voivodeship being named after a mountain range that takes its name after a monastery.
In Lublin Voivodeship, the Lublin Land is only a half of it. The rest are Podlasie, Polesie, and Chełm Land. Lesser Poland (of which Lublin Land is a part) is used in the name of a whole nother voivodeship (which doesn't encompass the entire historical region because of other voivodeships), and so is Podlasie. But you could argue that the name comes from the capital of Lublin, so no controversy here.
Overall, 11 of 16 voivodeships are named after historical regions. Some of those names cause people to misjudge the borders of said regions. Sometimes it's the outsiders (like in the case of people calling residents of Sosnowiec Silesians, which they are not), but it can even be the locals – like some inhabitants of the western part of Opole Voivodeship not realizing that they're a part of historical Upper Silesia. I've even seen one person from Żywiec arguing that their city is Silesian, just because it's in the Silesian Voivodeship.
All in all, I've wanted to ask if your countries have the same problem.
