I have searched for this topic but haven't found the answer I need. So in the Magic Guide it states that a RM database can only be linked to one Ancestry tree which is what I would like to do. I want to link my existing RM tree to the existing tree I have on Ancestry. But it appears that I cannot do that. It is stated that I have to create a new tree on RM and a new tree on Ancestry. I don't know how that helps me. My RM tree shares info and can be the same as my tree on Family Search. Why is this not the case with Ancestry? Is there any way to work around this? I know I cannot merge trees on Ancestry.
