I found this at the Emigration from Southwest-Germany website, and I'm not sure what everything means. would someone explain the parts I don't understand?

where is Gengenbach?
is Ungarn a place or unknown?
is the county unknown?

I have a vague idea that my Anton Wagner was from Engen, (Baden Wurtemburg) and that he went to Poland. I have no record of this, just exceedingly vague family stories. I have no idea if this is my Anton Wagner, but he's the only Anton Wagner that shows up at the site.
thank you for help understanding this record.
