DR. JOHN R. KELLS AND ANOR. v. DR. E. AKO ADJEI AND 3 ORS. Dr. John Ackah Blay-Miezah, traditionally known as Nana Ackah Nyanzu 11, Gyasehene of Benin in the Western Region of Ghana, during his lifetime comported himself and lead such a lifestyle as to make the public believe that he was one of the richest, if not the richest, person then in Ghana.  He died in Accra in 1992 leaving behind an estate alleged to value about forty two billion US dollars (US$42,000,000,000).  As to whether he did indeed have all that much is another matter.
