As usual, you give me another new piece of data. (The other marriage.) Thank you so much.
Yes, Frantiska was 18, and Vaclav was young, too. The first baby was born nearly two years after the marriage. They had eleven children in Moravia, and one born in the US in 1878. Vaclav died in an accident in 1888. Frantiska died about 1898, I believe.
