This may be of some help. If he is an author he will have a publisher, if you can find a book that he as written the Publisher's name and address or some other contact details will be in the book. I have found publishers very helpful though they usually will not give you contact details but rather work as a middle man between you and the author for the first contact , this is all now due to the privacy laws on this side of the pond. So try an on line library for a start, and find his/hers publishers if they have had a book published.
