When I went back and looked more closely, I found that Rosalia is from a different Lysacek family. Her record is on image 55. In fact, there was a 5th birth record at house 36, but since the father wasn't a Josef, I skipped over it. It looks like up to 3 families were living in 36. I've seen many with two, and the grandparents.
Do you need help in deciphering the records? You can go page-by-page and look for house 36. Since this is the most modern book, then you can go back to earlier books and look for house 36 entries, too.
