On several genealogy websites there are people who have my parents, myself and my brother in their family tree. I have tried to make contact. Most did not reply. They see a name they are looking for and don't don anyinvestigation whatsoever. They assume it's the person they are looking for and add them to their tree. A few who responded to me said they had no idea how that information got into their family trees. If they made the tree, they added the information. It is absolutely imperative that you know for sure you have the right person before you add them.
