Geni
I discovered this great little website called geni.com, which makes it super-easy to make family tree. It's quite addictive! I would link to my tree, except that I don't know how you set it to public, or if you can. However, you can invite your friends and family to join it and then presumably they can view it and add ancestors of their own. Anyway, I have learned a few things - for example I have an ancestor who was a perfumer and one who was a tailor/hatter! The one kinda weird thing is that Geni keeps asking me if I want birthday reminders for people who died circa 1857.
Now I'm off to roll on the birth ball (yes, when you're pregnant, exercise balls become "birth balls") for a while to help baby stay in the best possible position.
