This was an older post, but my family descends from the Joliet, IL Nemanich family. My grandfather was Charles John Nemanick, oldest son of Anton John Nemanich and Anna Marie Petrú. They moved from Joliet to St. Louis, where several of us still live. Charles had full siblings Anne, Thomas, John, and Edward. Anton had another wife, Mary Frances Nemec, and together they had children: Marie, Anton, Frances, Theresa, Joseph, Margaret, and Geneieve.
