I don't see why you're using this very customized numbering system for filing anything though. The numbers for your ancestors and the numbers for your child's ancestors will be different, and so will the numbers for your grandkids or your nephews and first cousins, although the ancestors themselves are the same. Most numbering systems are static, to nail down exact identities at a snapshot of time of publication. If there's a dynamic numbering system I've yet to meet it.
