Locating KAMINSKE relatives in Chicago

Good day All; This is especially to Carol Spielman. I believe that my great-grandmother, a MARIA KAMINSKE may be related to 'your' Kaminskes, as she came to Chicago from Pruessen/Pommerania at about the right time, and married a man that she met on the ship out of Danzig (modern G'Dansk, Poland). His name was Peter-Paul Rauchfleisch, and they were married in Chicago, I believe in about 1889. Two of their children survived to adulthood. I am a grandson of their son.
