After my mother died, I felt that my main link to the family history was gone. In my search to become better connected I foundAncestry.com and I joined. Since then I have had a lot of fun rediscovering my roots and putting together a family tree online.
Although I knew a lot about my maternal grandfather's family I have learned a few things about other family members. I just recently discovered that one of my great-grandfathers was born in Russia! I had always thought that he was Lithuanian but right now it looks like he had moved there from his birthplace.
An unexpected side benefit has been seeing trees from other members who have connected to my tree because of shared ancestors!
It's a little expensive, but as a shared expense within a family it would certainly be a good investment.
Works for me!
