I don't know if there is a connection, but some of your information is familiar.Jacob & Karoline Polacek arrived in the US @1903 with 4 of their 10 children.The rest of the children came at other times.There was a Jenny mentioned ina list put together by my grandmother & mother many years ago. The list states that Jenny married a Louis Seiden and had two children, Marcella & Alex. However, there is a question mark by that info and I've never been able to find anything else about her.The entire family eventually settled in Chicago.
The similarities in the spelling of Karoline caught my interest. Do you have any other info on her family?? Please let me know. Eileen
