I'm looking for my great grandfather, Johann Ludolph Gabriel Klenke, born April 13, 1857, at Klein Heuwisch, Schleswig-Holstein, and died November 23, 1945, at Karolinenkoog, Schleswif-Holstein. Johann married Anna Margaret Moeller, date unknown. She was born November 18, 1854, location unknown, and died September 12, 1923, location unknown. I've been unable to find any information about either Johann or Anna. Can anyone assist in finding information? Thank you. Karen, Minnesota, USA
