I'm trying to find my great grandfather, Johann Ludolph Gabriel Klenke or possibly Klinker, born 30 March 1857 In Klein Heuwisch. I think he died 23 November 1945 in Karolininkoog. He married Anna Margaretha Moller on 1 May 1881. Does anyone have additional information on the Klenke or Klinker ancestors? Thank you.
