Instead of a Comments section, it should be a Research Notes section on Deborah's profile, as well as on her 'current linked parents'. Include the wikitree IDs and names on her Research Notes and include her wikitree ID in each of the Parents profiles. In addition include other information / sources that indicate she is not a daughter of theirs, including any source citations, online links, etc, ie Christening citation, so others could easily find that reference. When you unlink them, the documentation will be in each of the profiles explaining the reason.
