A while back I needed to write up a fairly extensive family tree for something I was writing. It was not a serious project, but has since been converted into one. The author whose book I’m editing mentioned that he should probably start working on a family tree of the series he’s writing, so this is the link I sent him.
He’s already told me that he’s gotten a great deal of use out of it. It isn’t just a static template or any sort of pay to use business. Just a nice, easy to use family tree maker. You just sign up so it can keep track of your family tree for you (I’ve received no spam as a result of signing up) and you can also generate a link so you can show the family tree to others. It’s a really nice tool to have if you’re keeping track of a big family or just multiple generations of characters.
