Gwen’s sister, Gloria Steelman, also went to Mar-Ken.
From the Mar-Ken 1940 Yearbook:
From good ‘ole Glendale comes one of two sisters, Gwen Steelman. She likes the color blue but doesn’t particularly like the vegetable, radish (I know many others who agree with her, too!) Most all popular songs appeal to her, except the “too corny” ones. Her ambition is to become a singer. What does she mean? She’s already a singer and a good one, too.
From the September 27, 1940 Mar-Ken Journal:

From the October 25, 1940 Mar-Ken Journal:
