Family tree templates can come in handy even if you’re not a genealogist. For example, many of the professional photo managers I know use them to help with organizing photos by family and by date. They also come in handy for medical, historical, relationship, inheritance, and land ownership purposes. Some saga-writing authors even use them for keeping track of their fictional characters’ lives!
I often get asked what template I recommend.
My answer, as with oh-so-many things in life, is this: It depends!
