A museum in Saskatchewan says it would like to help a Toronto man who believes former prime minister John Diefenbaker was his father.
However, the Diefenbaker Canada Centre in Saskatoon says it does not have any items suitable for DNA testing.
George Dryden, 42, says his mother may have had an affair with Mr. Diefenbaker in late 1967 or early 1968 resulting in his conception.
Mr. Dryden does bear a striking resemblance to the former PM and says there have long been family whispers about his paternity.
He had hoped the museum would have items that could be used for DNA tests but its director says an extensive search has not turned up anything useful.
Mr. Diefenbaker was prime minister from 1959 to 1963 and it has always been assumed he had no children.
