Here’s one of a few articles Mary wrote by herself and that was published in columns like this from the Pittsburgh Press in 1935. Because television was not widespread and Mary’s voice was so mature, rumors flew as to her true age.  NBC even went so far as to publicize her 13th birthday but still much of the public refused to believe she was that young.  I think the same thing happened when people first listed to the Jackie Evancho Youtube clips.  Well she was indeed 13, but some people will always need to see a birth certificate I guess!  The odd thing was, many men sent engagement proposals to the radio station addressed to Mary, making it flattering and awkward at the same time.
