In my family tree on Ancestry I have discovered an error in my research which means that a branch of my tree covering 5 generations and about 70 people are not related to me. I would like to export that branch and create another tree not connected to mine so I can share it publicly as there is a lot of connections I have made between these people that I have not found anywhere else. I then want to delete that branch from my tree.
Is there an easy way to do this? I don't want to have to delete each person one by one, it would be too time consuming.
