For those of you who do not wish to read the entire links I sent you or have difficulties to find your German Bohemian heritage among so many German settlements, I will print the one paragraph that is most important in understanding the history of your ancestors: This is found under the title "Sudetengermans" I quote: "Before the Czechs reached the interior of Bohemia and Moravia in the middle of the 6th century, this land had been inhabited for more than 500 years by Germanic tribes, the Marcomanni along the Elbe in Bohemia and the Quadi in Moravia. In the 12th and 13th centuries, the Bohemian dukes and kings then summoned Germans into the country to be farmers, miners, artisans, merchants and artists to develop and to cultivate especially the hitherto very sparsely settled mountainous border areas. Centres of the territory were German cities such as Leitmeritz (Czech: Litomeøice; Germans city status in 1227), Eger (Cheb; 1242), Brünn (Brno; 1243), Pilsen (Plžen)1288), etc." Reference:http://www.z-g-v.de/english/aktuelles/?id=56 under the Subject Title: Sudetengermans.
