Her brother, George Russell, who was five years older than Gail, became a musician.

A talented artist, she starting sketching at the age of 5 and later grew into a respectable oil painter.

Gail attended Van Nuys High School and was in some of the same classes as actress Jane Russell.

Her blue-eyed, dark beauty was frequently compared to Hedy Lamarr throughout much of her career.

Her death certificate and the California State Death Record shows her date of death as August 27, 1961. Many sources give her date of death as August 26, possibly because her body, found on August 27, had been dead for at least a day. But August 27 is the official date of death.

In 1930, she lived with her parents George and Gladys Russell at 5306 S. Blackstone Avenue, Chicago, Illinois.

In Italy, most of her films were dubbed by Lidia Simoneschi and Renata Marini. She was also dubbed once by Dhia Cristiani in Wake of the Red Witch (1948).
