Well, to make a map might be usefull, BUT.....
It is very painfull part of our history, for both nations - Czech and German that for thousands years had lived side by side in these glass regions in Bohemia.
In many small towns and also villages was many anonymous painters, engravers, it is rather impossible to attribute all preciosly. You might be posdibly able to find the raw glass piece producer, but who and where it was engraved/painted you will probably never discover.
The difficulty and also pain is in this subject.
After WWII the majority of Getman spoken Bohemians had been deported, and really not very gently, to Germany. It was penalty for their former support of Adolf, even not all of them did really was big funs of him. Many villages had disapeared totaly and some of them had been renamed from German to Czech (Haida is Novy Bor, for example). When you will study the glass from 19th century, you will mostly find the German names of locations, and without deep knowledge it will be hard to find the nowadays name of it in Czech.
Seems to me that the best man who can help you is Dr. PETR NOVY from Musem if Glass in Jablonec n/N. He is the expert for this region and not only for it.
