I have not worked on this person in the Disproven Existence Project, but at the moment she is an exception to the principle that since people who never existed cannot have parents, spouses, or children, they should not be connected to any. In this case, Collineau is shown married to several dozen spouses, as a result of which it puts WikiTree in the position of making a quite dubious assertion. In addition, retaining the connections provides quite false information to anyone who is simply trying to produce an ancestral table of their ancestors, and the computer links them to Collineau.
I strongly recommend that Collineau be disconnected from all the spouses, AFTER links are put into all of these spouses in the biographical narrative, and AFTER a parallel note is placed on all the profiles to which she is currently connected.
As a Project Coordinator of the Disproven Existence Project I would be willing to take this on.
All of the people currently connectged to Collineau should also be assessed for whether they should be added to the Disproven Existence Project.
