To answer the obvious question, Michael Doyle (b. 1930) is not related to Sir Arthur, at least not so far as he's been able to trace, though there does seem to be a family resemblance. Although born and educated in England, Doyle settled in Canada in 1956 and has Canadian nationality. He is by profession an export trade consultant and is recognized as one of the world authorities on international trade and letters of credit. He shares Conan Doyle's interest in boxing and has even written a monograph called A Study in Sparring about Sherlock Holmes, the Prize Ring and the Corbett-Fitzsimmons fight.
