Concerning the Germanic languages, what should be noted, interestingly, is the "hybrid" nature of this language family: on the one hand, Germanic has a number of commonalities with the Baltic and Slavic languages, on the other hand, Germanic has a number of commonalties with Celtic and Italic.
In fact, each language is "hybrid". The current classification is only related to vocabulary. If you take phonology or grammatics, you can find mixtures between romance and Germanic languages (especially French), Celtic and Germanic...even between Basque and Romance ones (spanish). Of course, those influences can be modern.

However, in the Pyrenees region, we find exclusively Aquitanian and Iberian typonomy. Even areas that were clearly inhabited by Gauls in Antiquity show residue of Aquitanian. In contrast to that, there's plenty of Celtic name evidence in the Danube area. In so far, I find the case that the origins of the Gauls lay in Hallstatt/La-Tene pretty convincing.
Exactly. That's why I find very weird to search the original places of the Celts elsewhere than Central Europe.
