Our grandfather, Jaroslav, came with his mother, Anna, and his brother, Frantisek (probably your Franz). They had a sister, Rose, who stayed behind in Bohemia and never emigrated. Another brother, Josef, had come earlier, I think. I'm pretty sure they all ended up in St. Paul, but our grandfather ended up moving to Chicago. Anna and Mattes (the boys' father who came over later) ended up going back to Bohemia. There are some other details that we'll have to get from my sister.
I have a scanned photo of the family that I could send you, but I don't think there's any way to attach to these messages.
