Zetel, Schweinbruck and surrounding areas in the 1700s and 1800s

My ancestors came from Zetel, Dreifle, Schweinbruck and surrounding areas in the 1700 and 1800s. I am interested in learning more about those areas - what they were like during that time period. Were they primary farm land? Small villages?

Unfortunately, I do not speak German and I tend to think the information may be difficult to come by in English. However, if anyone has any descriptive information or can direct me to a source of some information, I would appreciate it.

Thank you,
