Everyday I have new tree hints that take me to a stranger's tree where my ancestor is included erroneously :( I suppose with the popularity of Who Do You Think You Are, a lot of people are turning to Ancestry to research their roots. Unfortunately, most people don't document or verify their sources. They just spot a familiar name on a member tree and add it to their tree and then share with their family members. I gladly share my info with people when we are connected, but this just bothers me that my great grandmother (or anyone else) is sitting in trees she doesn't belong in.
