How do I unmerge someone that has merge my ancestor into a tree who just seems to have found the best-fit person? I have messaged them and asked for the source of information for the merge as they seem to have merged my Louisa Selzer into their Lucy Selzer who married a Matthew Barron whereas mine Louisa married a Barrand and then added parents and siblings for her. They are either ignoring me or haven't picked up the message as of yet. I have always message before doing any merging and held off from merging when asked to and without knowing if these are for sure the same person it feels like it's corrupting my tree. I know dramatic but that's how it feels to me. I don't mind sharing information or documents or my research that's why my tree is here on this site and open.
I would like to unmerge mine from theirs until I have more proof they are the same person but I can't there is no option to unmerge on the merge, I don't want to delete it as this will affect other trees and I will end up with a duplicate. I just wished they messaged me beforehand. The other person is also just updating the documents many i had already found and added to mine, just saying 'same person' or ' the same person without saying why they are the same person or leaving any of my previous comments with a reason why for change but making it their change. Now, these could be the right ones but without more information via documents I have no idea. I do not have the time right now to go through with a fine comb as I personally do not add anything to my tree until I can say without a doubt it is them
There should be a button you both have to press before a merge so you can double-check and confirm not just have 2 people with similar names merged with no proper exclamation other than 'same person'.
