Parish records (not these censuses) are the MAIN source of information in Swedish genealogy. These censuses have some information extracted from a Swedish parish record called the husförhörslängd (HFL; often translated as household examination record or clerical survey record). The HFL is similar in format to a census but it is FAR more detailed and also was updated continually instead of being taken every ten years. The HFL is the main reason that Swedish genealogy is so easy.
My last post had a link which will guide you through using Swedish parish records as a source. I also suggested that you post on the Sweden forum.
It is possible to find information on the ancestors you are seeking but the search is time-consuming. I don't have time to do it for you. Perhaps someone on the Sweden forum will provide some answers for you.
