Your link to Vats does not have an entry #4 on that page.
The link to the 'leaving the parish' section of the Hovin church book lists a family of four leaving with intended destination of 'Nord America' --
Ole Olsen, Kari Steensdtr??, Ole Olsen, and Sigrid Olsdtr. The family appears to list a farm name something like Bakka or Bakken. (The 1801 Norwegian census shows a Bakken in Hovin -- then within Gransherad -- and possibly the parents of Ole Olsen, in-laws to Kari and the grandparents of the two emigrating children.)
The column headings for the "Afgangs-Lister Afgaaede fra Sognet Formedelst Bortreise" appear to be a a slightly older format that I would have expected to be used in 1841-1843.http://homepages.rootsweb.ancestry.com/~norway/na21.html
