Dear John: If you use the "Descending Book" it works just fine. It will list everyone - half-sisters & brothers, even adopted children. It is just when you try to go up from a certain person that it only lists those from whom you descend. In my case, I have eight half brothers and sisters. If I start with my name and go up the scale to my ggggrandfather, it will only show "MY" ancestors and will not show any of my half-siblings. I don't see how Bruce could make it do so. I tried going back to my ancestor, using my youngest grandchild. It only printed "HIS" ancestors, which did not include any of my half-siblings. If you start with the oldest ancestor and go down to the present, it will show everyone in your computer that is related to that ancestor. Virginia Kimes Pierce VPierce851@aol.com
