Please note the difference between category and location name. Categories for German Roots follow the current political organization not withstanding the name of the location in historic times. Categories for German Roots also do not include anything else but the town and state unless needed for disambiguation.
As for location the one provided by you has the following issues: "Evangelisch" is not a location, it is the religion of the individual in question, either Lutheran or Reformed; Mosbach as "Kreis" existed only from 1939 to 1973, Before that existed a "Bezirksamt" Mosbach which was much smaller than the later "Kreis". If used at all I think it is important to include what political entity is meant to help make sense of the changes in size over time; Baden in 1850 was the Großherzogtum Baden, a sovereign state not in Germany which didn't exist before 1871 but in the Deutscher Bund, a collection os sovereign states previously in the Holy Roman Empire.
