Danke! I tried to find a town on village named Kriegern in Germany but to no avail. Apparently it exists- strange perhaps how the German word for war- Krieg- appears in the gun making context- Krieghof in ULM-- etc..
You simply cannot use a dictionary of the modern German language to explain German names, especially place-names! Such names often are more than 1000 years old and are altered, transcribed and so on from long-forgotten meanings. the same applies to English names. For instance, English Warwick is not related to some sort of military candle, but was developed from Anglo-Saxon "waering + wic", spelled "Waerincwicum" in 1001, meaning "marketplace by the weir(= river-dam, German Wehr)"
