Searching for information on my Grandmother Rose Wollenberg. Her father was Michael Wollenberg; her mother: Maryanna Piotrowski. The Wollenberg family is originally from Grudenz, West Prussia. Michael and Maryanna also had another daughter: Anastasia. Anastasia is reported to have married John Mallack in Chicago in 1904. Rose married my grandfather, Paul Lewandowski in Chicago at St. Stanislaus Kostka Church in Chicago. Looking for connections and more data.
