The cutting does not actually say it was a Trust Fund but perhaps you have some other evidence? As it stands, something would have been held in Trust for a person, or persons until he/she/they died. If they died without issue, and the original Will had not given instructions as to what should happen after that the solicitors would have to trace down next of kin of the original will-maker. The solicitors' papers would not be public documents and are probably long since gone but if you get a copy of the Will you should be able to see what the original requests were and there would have to be public record of whoever the final Letters of Administration were given to. I think I would start by getting a copy of the original Will.
