Henry and Barbara Wohlmann must have had 5 or 6 children before they emigrated from Bohemia. They did not have more children after arriving to the US. On the ship's log it shows them traveling with 3 children. I know what happened to Antonia and Emma. The youngest one, Josef died before the 1880 census. I have never found evidence of any other children of theirs in the United States.
As for Antonia and Emma, as I have said earilier I found their marriage records but those do not show city of origin. So I have wondered if it is possible to find the marriage license for those marriages? Or if I could find out what church the Wohlmann's attended then I might find records of funerals of Josef and Henry and Barbara.
I know where Antonia is buried, but that was not in the same county and it was much later. I just don't think they would have listed her city of origin. I see that her funeral guest book just says she came from Bohemia.
The first link you provide is interesting. I can't read the language in the 2nd two links. Is there map which would show me where present day Jihocesky, Plzensky, Liberecky is located? My Wohlmann's had said they came from Bohemia in their 1880 census. In 1900 they said they came from Austria, then in 1910 they said they came from Germany. Does this give any clue?
