Burr reportedly got married at the beginning of World War II to an actress named Annette Sutherland—killed, Burr said, in the same 1943 plane crash that claimed the life of actor Leslie Howard. However, multiple sources have reported that no one by that name appears on any of the published passenger manifests from the flight. A son supposedly born during this marriage, Michael Evan, was said to have died of leukemia in 1953 at the age of ten. Another marriage purportedly took place in the early 1950s to a Laura Andrina Morgan—who died of cancer, Burr said, in 1955. Yet no evidence exists of either marriage, nor of a son's birth, other than Burr's own claims. As late as 1991, Burr stood by the account of this son's life and death. He told "Parade Magazine" that when he realized Michael was dying, he took him on a one-year tour of the United States. "Before my boy left, before his time was gone," he said, "I wanted him to see the beauty of his country and its people." After Burr's death, his publicist confirmed that Burr worked steadily in Hollywood throughout 1952, the year that he was supposedly touring the country with his son.
