I'm happy to share info if I know the people are researching the same family - however I made a mistake and for awhile one of my trees was public (now private again) and someone connected to it - taking the data I'd acquired. However they weren't the same family and as yet I haven't found a connection. In the end they did remove the connection.
If I spot a mistake and can prove it I contact them but not many are happy about it as they could have gone a lot further back on the wrong line (which I did initially too).
On OH's tree I connected to someone who said he couldn't be connected as the man never married!! lol - anyway he then got the certificates himself off scotlandspeople which he copied onto ancestry (I thought I'd given them to him so was in danger of being caught for copyright but I thankfully hadn't). However his public tree is now imblazened with illigitmate son of ........... and he isn't even a direct descendant which I did feel a bit iffy about.
