Martha Stewart.com has a great family tree that would be wonderful on a scrapbook page. You can find it HERE. There is a PDF of the template that you can download that link is HERE.
On M's site she has this framed and it looks lovely, but I was really thinking that it would be a great 2 page spread in a heritage album. Every family has at least one person who keeps the records of our family. You can be the one or help the person who does!
