Teresa, If you have clues that point to something being true, then it should be discussed in a Research Notes section in the biography. It should not be added to the data or stated as fact in the biography until the proof has been found and can be cited as the source of the statement.
I understand fully about this not being a full-time job - most people are in the same situation and WikiTree always urges members to allow plenty of time for other members to respond to contact or questions, as well as accomplish work on profiles, for this reason.
If I were in your situation, I think the first thing I would do is write to the person who took the things off and start a discussion with them about it - they may be able to help find proof, one way or the other.
