Hi, I think Wenzeslus Pivonka is my great grandfather. Much of the info you presented is similar to what I have but also a bit different. My grandfather, Michael, left home very young, so it has been hard to gather info for that side of the family. Here is a bit of what I have:
We knew my ggrandfather as Wencil (b1852 in Bohemia) married to Ledvina (Anna) Sokup (b1850 in Bohemia). Children were Michael, George, James, Mary, Netty, Annie, Elizabeth, Suzanne and Wencil. My info is largely undocumented, mostly from the 1880 census and our own family records.
I would love to get more info - feel free to contact me direct at
