H. Rosenkranz provided a detailed explanation for the place, which initially had two names (Bertoldisdorf and Hunthobit). It is best to reproduce the entire section here:
In one case, a Latin document (here reproduced in German) from Heinrich, Vogt von Gera, from 1262 gives us an insight into what happened when the town was founded; Namely, it is talking about 'my feudal people who I have in the village that is called Bertoldisdorf and Hundhobit, namely Hermannum Scultetum and the sons of Berthold Bachschenkel. This shows that Bertold Bachschenkel founded Bertoldisdorf, named after him, on behalf of Vogt Heinrich, but left his property to his underage sons in 1262, which is why a man named Herman took over the office of Schulzen (located in Scultetus). The addition and Hundhobit suggest that when Bertoldisdorf was founded, there was already a small settlement in the area around the Hundehaupt. Both were probably united soon after 1262, because in 1278 it is called Berchtoldistorff, that is Hundheubten, of which only the second place name remained (1289 Huntheubten, 1378 Hunthoyten), which is now Hundhaupten, southwest of Gera.
