Prince William’s bride-to-be has a personal connection to Calgary.

The public is finding out that Kate Middleton’s grandfather Peter Middleton spent around two years in Calgary during World War II, working for Britain’s Royal Air Force.

The place where he was stationed is the very land the Calgary International Airport and Calgary Aero Space Museum now sit on.

Genealogy website Ancestry.ca recently discovered an old air passenger list with Peter Middleton’s name on it, listing the Calgary flight school as his last permanent address.

Lesley Anderson with Ancestry.ca tells 660News the list led them to find out more about Peter Middleton, who was in his early twenties at the time.

“He spent some time as a flying instructor and it was two-and-a-half years before he finally saw action,” she says. “But he joined a squadron in Kent in August 1944.”

Peter Middleton died in November 2010, but did get a chance to meet his granddaughter’s fiance Prince William before his death.

The royal couple is scheduled to visit Calgary in July.
