Of the three sources you cite, I do not see any proof or reference to documentation to substantiate their statements so I lend them only the credence of hearsay, as with all of the oral histories.
Which leads me to your comment regarding oral histories, I do think the oral histories are equally valid and their conflicting statements need to be documented and held.
Putting the discrepancies on the profile under a research notes or conflict section gives researchers the ability to see what the conflicts are and what types of information they might want to look for to prove or disprove the associated theories.
I again state, it is not the duty of the profile manager, especially in profiles this old, to control what is put on the profiles or control contribution. As recommended by wikitree guidelines these profiles should in fact be open to a green level of privacy because they do not contain sensitive and private data that needs to be protected. It is a violation of the spirt of wikitree to, as you stated, have the profile manager control what goes on a profile.
