Baby Peggies, Sunday 26 August 1923
According to her Wikipedia page, Vancouver already had a Baby Peggy, whose first birthday happened to fall on the day the winners of this contest were selected. Yvonne De Carlo (bottom photo) wrote in her autobiography that
I was named Margaret Yvonne – Margaret because my mother was very fond of one of the derivatives of the name. She was fascinated at the time by the movie star Baby Peggy, and I suppose she wanted a Baby Peggy of her own.
