My dad is doing ours!! He's really into it and we've found out a lot about our family that is really interesting! I don't know much about my mom's side of the family though and kind of am leery about knowing stuff. My grandpa was a really rough man and I'd hate to know more about his background or his family's. I know that's not nice but I'd really hate it if I found out my maternal grandfather's family helped to kill the family on the paternal side in the Holocaust.
Sorry to bring your thread down.
On the plus side though we did find out about a town in Wisconsin my great great great grandfather founded! That's cool. His cabin is still there.
