The noble free from Dalwigk come from the village of Dalwigk, southeast of Korbach, first mentioned in 1036, destroyed since the Thirty Years' War and today desert.
You were Ministeriale of the Corvey Monastery and its Burgmannen at Lichtenfels Castle in Dalwigksthal in the Waldeck-Frankenberg district. They were then feudal people of the Counts of Waldeck. Over time, members of the family were also feudal men of the Landgraves of Hesse and the Archbishops of Mainz.
Today the family consists of two families, both of which go back to Elgar von Dalewich: the barons of Dalwigk (Dalwig) zu Lichtenfels and the barons of Dalwigk zu Schauenburg.
The Dalwigk zu Lichtenfels also included the Silesian barons of Dalwig, who go back to the Prussian general Georg Ludwig von Dalwig. They stood outside of the feudal association because Georg Ludwig was an illegitimate son of Lieutenant General Rabe Ludwig von Dalwigk, but received Prussian recognition for the use of the title of baron through various rescripts of the Prussian heraldry. The Silesian Dalwigs are extinct in the male line.
Another branch of the family went to Unterbach, whose area at that time now belongs to Düsseldorf and Erkrath. There he owned the water castle Haus Unterbach from 1708 to 1807.
