Well done! I made a couple family tree templates too but I really like what you've done here.
When I get some time I'll diagram an example to show how things really fit together. I use this one for trying to clarify how my client's family relationships affect their life.
This is nice. Good place to start from. I can imaging lots of copies and pastes of the images into my chart.
Okay, I have an example posted. Please, take a look at this and let me know if I'm missing any relationship types that should be listed on a family tree. These are designed more for an outsider trying to get to know the family than what the family would use for real genealogy.
