I have a Josephine (Jozefa) Kasperska, my ggrandmother, born abt 1867 in Germany or Poland. She came and settled in Philadelphia. I haven't found any immigration record yet, but only did limited searches on the internet. On the records I do have, some list Kasperska, some list Kasper. Some records say she was born in Germany, some say Poland. I know at that time, many changed the name and didn't let there kids speak anything but English to blend in and they hid the fact they were from Germany. The family story passed down to us, was my ggrandfather (also German) escaped from the Kaiser. So try looking for her under Kasper too, it's probably German or Poland.
