After all the many family group chart organizational systems I've tried, I
find the easiest one is the color-coded system I learned at the FHL that
corresponds well to the fan chart in Family Tree. I don't number my
families anymore because when I did I still had to have some kind of cross-check
index to tell me what a specific family's number was. I prefer to have
related groups filed together. The colors on internal file folders within
hanging files show my father's father's lines as one color,
father's mother's as another, and the same thing goes for my
mother's father's and mother's mother's lines. The colored
groupings are in file boxes I alphabetize by surname (or given, if no surname
exists), and I put same-name families in order by earliest birthdate to latest.
All information about a person until he's an adult goes into his
parents' file. After that time, he has his own file. Collateral lines are
filed alphabetically behind closest relative grouping. It's terribly simple
conceptually and I can put my hands on what I need very quickly.
For me, Personal Ancestral File is the ne plus ultra of family history data
If you like that, you should love RootsMagic as a next step up, one that is
upgraded as often as needed (which you know won't happen anymore with
Personal Ancestral File). It's got all the extras needed for new
genealogical technology, syncs beautifully with Family Tree / FamilySearch, and
is remarkably inexpensive and easy to use. Much of it will look the same to you
because the principles and basic steps involved are very similar to PAF.
