My husband's grandparents are from a part of Norway where there weren't a lot of people, so have many common ancestors. But my Reunion 12 file shows many fewer than my Reunion 11 file, which I fortunately still have. (Reunion 11 is consistent with the numbers in earlier versions.) I can't think of anything I have changed since converting the file. Is there any easy way to get reports from each to see which are missing in Reunion 12?
