He died 25 September 2004.
Interestingly I have a note against this man in my copy of Debrett's stating d 2004, but cannot find where it was reported to the group - it might be possible I intended to, and forgot to?
He was the son of Frederick William WISEMAN (1885 - 1955), scion of the baronets of that name (descended from the 6th baronet), and Charlotte Hepzibah WARD (d 1966).
