Sounds like it's time just to look at the evidence, not what others have made of it. Start a free space page (or do it offline) and only list primary sources. Wills, actual BMD records, property transactions, whatever. No user generated stuff at all. That should clear the air. If you cannot find enough material to come to a conclusion then you have to ask yourself how others did. Could take some time. It'll help to edit your question to include the ID of the profile in question so that the rest of us can find it easily when we're being nosey. (Nosey people make very good sleuths).
