This challenge may be difficult, so I'll give you a head start.
I Love Lucy premiered on this date in 1951. Kathryn Card, the actress who played Lucy's mother, was born Oct. 4, 1892 (supposedly in Butte, Montana), and died Mar. 1, 1964, in Costa Mesa, California. Her entry in the California Death Index says she was born in Missouri, perhaps because someone coded Montana as "MO" rather than "MT". Her mother's maiden name was McCurdy, but what Kathryn's maiden name was is not clear.
Searching for women named "Kathryn" born about 1892 in Montana turns up a Kathryn C. Sullivan living at the Neil House Hotel in Columbus, Ohio, in 1930. She was married (age at first marriage, 18), but living without her husband. Her father was born in New York, her mother in Massachusetts. Her profession, oddly enough, was "Actress-Theatrical."
Was this Kathryn Card? What else can you find out about Kathryn's life before Hollywood?
