[Ger-Poland-Volhynia] Grudzienski Alternate Name

[Annegret Krause]

So it could be, that Grudzienski ist simply the Polish translation for
Kluth or Kloth.
"Gruda" is the Polish word for clod of earth and
"Kluth"  the Low German word. In my region (Lower Saxony in Germany) the
plural form is spoken "Klueten" (with u Umlaut) or "Kluten". The High
German word is "Klumpen".
