How Ilyena became Helen Mirren
The name change happened long before her acting career. Her father, Vasily Petrovich Mironoff, anglicised his first name to Basil, and in 1951 he changed the family surname to Mirren by deed poll, a change recorded in The London Gazette.
So unlike most names on this list, "Mirren" is her legal family name rather than a stage name.
