Hey, kicking the hornets nest happens, no fault of your own.  Let me just give you fair warning though, that the editor who initiated the move request has a long involvement in this, and all those folks that are supporting this move along side you are the native German speakers who were adamant against any form of compromise.  A bit weird they all show up within a couple days, isn't it?  LOL  The editor who made this move request regularly communicates offsite through e-mail, hence my suspicions.  Anyway, you'd think people could compromise, wouldn't you?  I guess history tells us that some humans are not capable of compromise...  So, anyway, as far as your research, and I'm not sure where you are based, but if you are in the United States, try dropping by a Whole Foods, etc.. and you'll see that products from this region are labeled as coming from Alto Adige.   This is a marketing decision made by inhabitants of this province.  Look, I'll be the first to agree that both South Tyrol and Alto Adige are used in English,  it is really about 50/50 (especially in the UK).  In the US it is almost completely Alto Adige (because our interaction with Bolzano is mostly thru agriculture).  Here are some examples of Alto Adige being used  and .  Yes, the German speakers can make similar arguments for South Tyrol usage, and we can go on and on and on.  That is why the original compromise was made, to use Alto Adige and South Tyrol in the lead paragraph, and use the Province of X location (as is done for every other province of Italy on Wikipedia) for the article.  But, some German speaking editors could never accept this, and want this article to match the German Wikipedia article, Sudtirol.  Ever wonder why they constantly remove Alto Adige from bold face and any statement recognizing its use in English?  Anyway, I really hate to even participate in this nonsense anymore, but this move request is nothing less than abuse of Wikipedia (but, hey, what's new).  The same old editors are trying to come in here and flood the voting to change what was a decision made thru many weeks and months of discussions, and to a naming convention that is clearly biased towards a German point of view.  So, I don't doubt that your intentions are genuine Dohn joe.  Be wary of what is going on here though...
