Thank you for all the work you did on Joseph Vosmik. It is not him, he was born in 1858 and arrived in 1891 per 1910 census. He brought wife Mary (born 1859 and called Irma in his obituary notice), son Joseph (born 1882) and daughter Anna (born 1887). I know this is the family, as my grandmother was one of the children born here. I just found a dictionary to help translate Czech genalogical records, and now know that he came from Pisik, Bohemia. But still no knowledge of how they got here. Do you know if those coming to Chicago tended to enter by a specific port? I know that Ellis Island was not yet open in 1881.
As for the Jozwiak family - my grandfather was Joseph Henry Jozwiak, born June 30 1896. Father was John, born about 1870 in German Poland and arrived in 1893. Mother was Francis (don't know maiden name), born about 1870 in German Poland. Arrived in 1892. All lived in Chicago. No Ellis Island records found for John, know that Francis will be difficult without maiden name.
Any direction you could provide would be greatly appreciated.
