Kate Middleton's Canadian connection traces back to her late grandfather Peter Middleton, to whom she was quite close. Her grandfather (who recently passed away) was a former Second World War Mosquito pilot.
Peter Middleton made two trips to Canada during his youth. He visited
Quebec, when he 17 years old, on a "
school empire tour party!" in August 1939,
and he served at least two years at a Royal Air Force base in
Alberta.
