I have in my file Johann Goetz from Loucim town. He asked on 1882 for issuing of emigrant passport to USA.
There was and still is surname Koutnik common in this area. Janovice town is abt.15 km southeast of Loucim. Both towns are in southwest Bohemia - Loucim in Domazlice district and Janovice in Klatovy district.
The parish registers of them are in the archive in Plzen. You can search yourself there or you can hire some of Czech researcher.
All the best. Tony.
