[Hermes777]

I wouldn't commit myself directly to the Ladin dialect now either. It refers to a region.
Perhaps it is also an unfortunate choice.
There are also Rhaetian, Dolomitic and Friouli.

Here, one should learn something about the empires of Raecia and Noricum and their languages, and the development up to the present day.
Invasion of the Roman Empire by the Bavarians and Alemanni around 500.

I personally exclude the German language (Alemannic) from the Swiss side. I can't see it in the VM like that. But the Bavarian language is. Therefore rather from the eastern side (Carinthia).
I think I would recognise my dialect.
Here is a language example. Imagine that in an Italian crossroads.

Scanning over the voluminous and very uneven history of Voynich theories, there is a substantial body of opinion that places the ms. in alpine northern Italy. But such theories then diverge east or west. It seems the larger body of opinion looks towards the west and the Switzerland side of northern Italy. I am not sure why, although people are often guided by the French month names on the zodiac pages. 

I find a much stronger case for eastern alpine Italy - the Tyrol. As you say Aga, it's a region, and it has a very complex linguistic history.
