Mary Martin, disappointing to read that she ditched little Larry and her husband to have a career, Larry lived with his grandparents repeatedly whilst Mommy was out becoming a star:
“In an odd twist of fate, Martin’s dance studio was burned down by a local man who thought what she was teaching was sinful. At this time, her father encouraged her to end her marriage, saying she was too young, and Martin left for Hollywood, leaving her husband and son Larry behind.”
