Am seeking local Polish info on my ancestors who emmigrated together from Konitz, West Prussia (currently Chojnice, Poland) to East Tawas, Michigan, USA, in 1885. They were Albert and Eva Roggenbuck, their daughter Caroline, and Caroline's husband Carl Müller (known as Charles Miller in Michigan). Carl and Caroline were married 5 Nov 1880 in Konitz. Carl's parents, who did not emmigrate to America, were Lüdwig Müller and Rosa (neé Czysz). Had no luck searching for any of the above in Prussia via LDS's on-line IGI index.
