The Swedish Church Records date back to the 16th century. The earliest records are birth/baptismal, confirmation, marriage and death/burial records.
Later records are for example church ledgers, moving-in and moving-out registers, and household examination rolls.
The book of examinations lists every family or single person living in a parish. The records are updated every year with notations of names, dates, movements, knowledge of the scriptures, vaccinations, literacy, disabilities and more.
If you are lucky, and the vicars have done their job, you can follow a family through the years.
This works in theory. Sometimes church records are destroyed by fires or there might be a notation missing of which parish a family moved to.
