Have you done any work on the 6 siblings?
There is a possibility a clue regarding Bryan might turn up while checking them out, might be god father to nephews/nieces perhaps...... and you have looked for a Will of course.

Was he the first son as he was given his father's name? (Though, don't know how that helps!!)
