I was interested in the Dollarhide numbering system. I have a paper copy of the system. He had a program during the DOS days, but it was purchased and absorbed by another program. His system based on a combination of Ahnentaphel/Pedigree and the Henry System. A person would have to decide on who was going to be the beginning number - themselves or their children and go from there. Even the inlaws and step children got numbers. That would require keeping a list of the numbers even if they were logical. When I first used PAF Version 1.0, a very nice book came with it which gave instructions for numbering your documents. They suggested using the first 3 letters of each surname (or a unique first 3 letters) and adding the numbers sequentially. Unfortunately, I am not that well organized and didn't keep up either system. Betty
