Chet, I can trace my Great Grandmother Frances Wojciechowska Gruczewicz's sisters to the Chicago area. From what I understand they immigrated prior to her arrival in 1906/1907. They are Mary (who married Joseph Kowaleski), a Florence (who' married name was Mikwaszewicz-Norkus) these 2 sisters at one time lived in Waukegan. Another sister Hedwig "Hattie" (married Radzinski) who lived in Chicago most of her life, Anna (who married Gapszewicz)and spent most of their life in Hammond, and a Josephine who remained in Poland. Their parents were John Wojciechowski and Teresa Bogdanska, is there any connection to your ancestors? If so would greatly appreciate sharing information.
