Rosie, I have on occasions found one of my relatives on a tree to which they have no connection other than the same common name. I have gone to the trouble of researching their person and provided them with all the references to check for themselves. Only to be told they know their facts were correct. You can't convince some people no matter how politely you do it.
I have one person in my tree born in Essex, married in Essex and can be found in all the census. Plus I have had contact with her descendant. Yet someone has her married and living in Dorset. I researched the Dorset namesake, found her birth in Dorset and in all the census after her marriage her birthplace as given as Dorset. That didn't convince the tree owner.
Another tree has one of my great grandfathers born in Dorset, apparently taking a fly trip to America in the 1800s having a family there at the same time as having a family in Dorset , had that been the case I would not exist.
I could go on with a long list of similar errors, it is a waste of time trying to help someone if they can't accept they made a mistake. Personally I would much rather be told if I have slipped up, than continue wasting time and money adding the wrong person to my tree. We are all human and no one is infallible.
