Michael Lindsay-Hogg was born in New York City in 1940 to actress Geraldine Fitzgerald. He was educated at Trinity School in New York and at Choate School in Connecticut. For most of his early life, he understood that his father was Fitzgerald's husband, Sir Edward Lindsay-Hogg, to whom she was married until 1946. When Michael Lindsay-Hogg was 16, his mother reluctantly divulged that there had been pervasive rumours that his father was Orson Welles, and she denied them—but in such detail that he was left confused and dubious. Fitzgerald evaded the subject for the rest of her life.
