William Cagney, the producer brother of the renowned actor James Cagney, bore an uncanny resemblance to his more illustrious sibling, with their physical appearances being almost indistinguishable.
When his first wife, Boots Mallory Cagney, gave birth to twins, Cleveland (Cleve) and Steven (Steve) Lewis, on February 19, 1941, her younger sister Viola "Bodie" Mallory Avinger, who was also Boots' sister, had identical twin boys.
Boots, who had always wanted twins like her middle sister, soon after adopted fraternal twins, Jill and William, with her husband Bill Cagney, thereby expanding their family and adding two new members to their household.
