I am looking for any families who lived in the towns of Gross Schmuckwalde or Theuernitz Osterode East Prussia who would have known my Great Grandparents Friedrich Konopka and Louise Galka Konopka. Last heard of in 1914 when Caroline died. My Grandmother was married in Gross Schmuckwalde on 26 Nov. 1889 Caroline Konopka to gottlieb Chmilewski. They immigrated to the US right afterwards.
Thank You for any information.
