Hi,
I live in Muszyna, Poland and I know about one family that moved to the USA in 1909. First it was Kacper Rutowicz in 1909 and in 1912 his wife Katarzyna joined him with their 5 children (Józef, Maryanna, Aurelia, Antonina and Antoni) and so the family united. Katarzyna's maiden name was Kalucka and this way she was related to me. I know they all headed Sioux City and Kacper lived there between 1909-1912.
