I'm looking for information on Vaclav Schwartz who was born in Pesek, Bohemia. He married Katerina Vinc and she was from Hungary. They had at least one child together, Frank Schwarz (many variations of the name have been seen). Vaclav also had a son, Joseph (Josef) who was considerably younger than his brother Frank so I believe they may have had different mothers. Although, Joseph's mother is unknown at this time. BOth of his sons lived in Chicago at the time of their deaths. I am unsure if Vaclav himself came to America as well. I'm looking for ANY additional information on this family.
