Magdalena Grodzka-Guzkowska - A Lucky Woman

From CBS News:

Magdalena Grodzka-Guzkowska's journey of self-discovery is pieced together from interviews with her and people close to her, emails made available to The Associated Press, information provided by Yad Vashem, her memoir "Lucky Woman," and documentary footage.

Decades after she helped save the rabbi and about a dozen others, mostly children, by teaching them Christian customs, Grodzka-Guzkowska discovered documents in an old suitcase showing that her father and other close family members were Jews. Growing up she knew vaguely that one of her great grandmothers was Jewish but nothing more about those roots.
