Winters-Vernon passed away at her home in Vista, California on 14 August (10) after a battle with pneumonia, her family tells The Los Angeles Times.
As Gloria Winters she enjoyed guest acting roles in numerous 1950s series, including Richard Diamond, Private Detective, Racket Squad and Death Valley Days - but she was perhaps best-known for her role as Penny in TV western Sky King.
She retired shortly after the series went off the air in 1959 but found love on the hit show before she quit acting, marrying Dean Vernon, a sound engineer on Sky King who died in 2001.
The Sky King role also inspired her to write an etiquette book for young girls, entitled Penny's Guide to Teenage Charm and Personality - which inspired alternative band Nada Surf's 1996 song and video Popular.
Winters-Vernon is survived by her sister-in-law, Phyllis DeCinces.
