We just learned of the of Qwen Russell’s passing. She died in December of 2020. 

Gwen was the daughter of Ruth Knolwes and step daughter of Howard Knowles. 

Gwen went by her step father’s name, Knowles when she was growing up but her birth name was Holland. Gwen was the widow of Ira Russell who was in the class of 1951. 
I believe Gwen was living in Ridgecrest at the time of her death. Her brother, Bruce Knowles, was in the class of 1964 and her brother, Kenneth Knowles, was in the class of 1967.
