It is all very well you folk with a private tree saying that all someone has to do is to ask you politely for details about a person and you will tell them - but your answer will never reveal the full picture. We won't see the actual Timeline of the person we ask about, which would probably give the full, rounded picture of that person's life.
...The person asking for the information may never be told the names of all children involved, may never get to know if any of them went to Australia, Canada, NZ, or USA, and may never know if anyone was married several times. When asking for information about someone from a Private tree, do we really get everything that we would really love to know?
No, all we usually get back, (if we are lucky, because sometimes we get no answer at all), is a brief answer to our question and that's all. We won't know about all the extra information on the Timeline. Someone with a Public Tree reveals all this at a glance on every Timeline of every ancestor, often accompanied with birth, marriages, and death certificates, not to mention images of Ships Passenger Lists, gravestones, etc etc etc - but folk with a Private tree aren't willing let us see their work at all.
I am not shouting folks. Too old for that. Just explaining my point of view.
P.S. I don't mind folk taking images or information from my tree, it is just that I would like to see theirs too.
