The parish was divided into several groupings for each husförhör, the meeting at which the people were asked questions about what they knew about the Bible, Luther's Catechism, etc. Each group met at a predesignated home for the exam.
Here are some images of a husförhör, the session at which the priests tested people in the parish and wrote information in the husförhörslängd.
Scroll far down on this page.
Some HFL books have a listing in that book of where the husförhör groupings would be held at a particular period of time.
I found this information in Frändefors parish in Älvsborg county about locations of each husförhör group in 1824, 1825, 1826, 1827, and 1828. In this case the priest put the schedule at the end of the book. Perhaps you will find your family listed as the hosts for the husförhör if you look carefully at your own HFL books.
