The Lord of the Rings Project is a massive family tree created by Swedish student Emil Johansson to highlight all the familial connections between characters in the series. It contains over 800 characters and can even be modified to display only dwarves, hobbits, muggles, etc. My family tree? My family tree looks like the kind of branch you'd make a slingshot out of (I'm from West Virginia).
Thanks to Erik S., whose family tree looks like the tree of life: full of diversity. Good for you, really. I TOOK A COUSIN TO PROM.
