"Brown" OK, but middle name Gordon? I don't remember seeing that kind of thing too often.
Possibly the doctor treated the middle and last names like an "unhyphenated" final name. Like the creator of Sherlock Holmes. Technically Sir Arthur Aloyisius Conan Doyle (the "Aloyisius" surprised me too when I came across it) is not "Conan-Doyle" but "Doyle". Or in the other way, England's great Prime Minister from the Second World War. It is not supposed Sir Winston Leonard Spencer Churchill (as though the third name is like the first name of the assassinated Prime Minister Spencer Percival). Rather the family technically is the Spencer-Churchill family when the direct line from the first Duke of Marleborough died out and a second group of descendants were allowed to take the title by hyphenating their name (sometime during the Napoleonic Wars - a First Lord of the Admiralty, Lord Spencer, got permission to do this). So actually the Great Prime Minister is Sir Winston Spencer-Churchill. However, the Churchills eventually dropped the hyphenating of the last name.
