But this does NOT work well for real life genealogy. Think of step/half families, etc. No, better to look at system's that deal with this. Look at GEDCOM, genxml, or similar systems. I know I have seen several gedcom -> sql schema's out there, some for mysql even. There are also several systems for archiving information such as family events or media, and linking those people to that data. -- Jayce^
