Herbstreit is what I believe the German version of this name, and it is a common name in south-west Germany.
Familysearch gives:
Johannes Baptista Herbstreit, son of Sebastian Herbstreit and Maria Anna Kuenstler, bapt. 25 May 1795, catholic, in Ettenheim/Freiburg, Baden, Germany.

Maybe this can be a starting point for further research. I think there is another Ettenheim in Baden, near Offenburg, where also Herbstreits may have lived.

The churchbooks of Ettenheim are availiable online in there original scans, but they are hard to read. Take a look here:

Then click on the link "Zum Bestand südbadischer Standesregister" and choose "Ettenheim" in the list on the left side of the page. The different books will be listed in the main frame and you are able to look at the images.
