The baptism record that you have for Daniel, is it for Christ Lutheran Church?You listed it as Christ Evangel. Lutheran Church, I'm not sure if they are the same or not.I extracted all of the Wollet information from the Christ Lutheran Church records, but I don't have Daniel's listed.
I believe that you are correct that Daniel would have been another child of Frederick Wollet and Elizabeth Kolb.Daniel and Catharine are both buried near her parents at Prospect Hill.Frederick Wollet is right there with them as well.
There is one other child that I found in the church records for Frederick and Elizabeth, Elizabeth Wollet born 27 Feb 1824 and baptized 4 Jun 1824.
Interesting too that I do not find any of Daniel and Catharine's children in the Christ Lutheran records, nor is there marriage record there.So they must have attended another church.If you know what church that may have been, please let me know.They had what looks like 4 children die young with no dates for tombstone inscriptions.Those children are:John F., Josephine, Mary M. and Emma.
