Shel's dad, Vernon, introduced me to a website I really like. It's called FamilyLink. It's a genealogy site associated with Facebook. I've managed to put together a decent little family tree just from what Shel and I could remember off hand and what I could copy of Vernon's work.
I've always thought that genealogy was fun, but it can be a tremendous lot of work - not just to create, but to peruse and enjoy even. This is pretty simple and intuitive, so I'm sold.
