Jakob Jelinek, right? Jelinek is another well-known name here is Nebraska. It's always fun to see the "Amerika" notations in the records. That way, one is pretty sure that is the ancestor. My curiosity got the best of me, and I looked for a bit to see if they came in 1872 with the Coufals. A group did, but this child was not with them. The father was Jakob, but the mother was Josefa, not Frantiska as in this birth/baptismal record. So it had to be a different family.
It would be so easy to get distracted and follow the Jelinek path.
