As this is your umpteenth message on this subject, you must be quite desperate. I don't know anyone you mention, but there is an entry in the Manx telephone book that might be of use - I would suggest a short, simple, unemotional letter to this address to introduce yourself - they may know the people you are seeking:

J.A. Corran, 1 Greeba Road, Willaston, Douglas, Isle of Man

I hope it works out for you.
