Update on Jan (John) and Josefa Plucinski. Jan and Josefa immigrated to Chicago in 1890 probably from the Kalisz, Posen area of Poland. It is known that Jan had a brother Lorenz who immigrated about 10 years later and settled in Milwaukee, WI. Looking for other Plucinskis from the same area in Poland - possibly other siblings or cousins. It is possible their father's name if Ignacz.
