Please contact me as I am researching the same Kopitzke family. My grandfather was Arthur Kopitzke (1894-1969), a brother to Adolph John Paul Koptizke (1910-1996). I have our line back about 3-4 more generations, and as many descendants as I can gather. My mom recently told me the Kapitzke family line buried at Baldwins Mill Cemetery in Royalton Township, Waupaca County, Wisconsin are supposedly related to our Kopitzke line.
