Welcome to Rootschat. There have been lots of topics on here about Ancestry public trees, and they all complain that there is a tree, or more, resembling their own tree but with wrong info. There is not a lot you can do, if you try to write to the person with the "wrong" tree, either you'll not get a reply, or you'll get a reply telling you they are right and you are not.
The best thing is just to grin and bear it and know that you have the correct info, researched and with certificates etc. to prove it.
