I created a profile of a sibling to my great great grandfather that I only know for sure they share a mother, but not a father. I merged this new profile with another tree only to realise that it had automatically adopted both parents of my great great grandfather as parents. This has created a problem.
As a work around I removed the earlier entry but the link to the other tree still seems there. The link is correct but the parentage it points to is messy. If I were able to merely unmerge these mistakes it would make life a lot easier.
Assistance would be greatly appreciated.
