Who's Who today for Brit Hume (full name: Alexander Britton Hume). He was born June 22, 1943, and his parents were George and Virginia Powell (Minnigerode) Hume. Paul Hume did not marry until 1949 and was only 27 years old when Brit was born.
Truman called Paul Hume "a frustrated old man" at the time of his panning Margaret's singing; at that time Paul Hume was 35 years old and President Truman was 66.
So what is the relationship between Alexander Britton Hume and Truman's nemesis, Paul Hume?
