Lizzie Halliday: The Horrifying Tale of America’s First Electric Chair Nominee

Discover the chilling life of Elizabeth Margaret McNally, the County Antrim native dubbed 'the worst woman on earth' after a violent spree of murders that left 19th-century America in shock.
Elizabeth Margaret McNally, a name now largely lost to time, was once labeled the ‘worst woman on earth’ at the turn of the 19th century.. As Misryoum explores the archives of criminal history, the story of this County Antrim native remains one of the most chilling accounts of domestic terror in American history.
Born in 1859, McNally emigrated to New York as a child, growing up in a city that would eventually witness her descent into a pattern of calculated violence.. By the time she reached adulthood, she had developed a volatile reputation that led to a fractured relationship with her own family.. Her path through life became a trail of suspicion, marked by a series of marriages where husbands died suddenly or vanished into thin air, leaving behind a wake of financial ruin and unanswered questions.
A Trail of Arson and Murder
The trajectory of her crimes shifted from insurance scams to cold-blooded slaughter.. After serving time for arson in Pennsylvania, she adopted the name Lizzie Halliday and moved to a farm in Sullivan County.. It was here that her penchant for destruction reached its peak.. Following a series of suspicious fires—most notably one that claimed the life of her disabled stepson—the truth about her presence on the farm began to unravel.. When police eventually swarmed the Halliday property, they discovered the bodies of the McQuillan sisters buried beneath the hay, followed by the gruesome remains of her husband hidden beneath the floorboards.
The legal proceedings that followed in 1894 captured the nation’s morbid curiosity.. As a journalist for Misryoum notes, the trial was a spectacle of chaos.. When sentenced to death by the electric chair—a pioneering punishment at the time—McNally attacked the sheriff with such ferocity that he later required an amputation due to infection.. Her behavior in court, alternating between incoherent gibberish and calculated violence, fueled debates about her sanity that persisted long after her sentence was commuted to life in a mental institution.
The Lingering Legacy of Violence
Even within the walls of the Matteawan State Hospital for the Criminally Insane, McNally remained a source of terror.. Her 1906 attack on a nurse, involving over 200 stab wounds with stolen scissors, proved that incarceration did little to dull her homicidal impulses.. This act of brutality underscored a fundamental question about the era’s justice system: was she truly mentally ill, or was her behavior a manifestation of a predatory nature that authorities were ill-equipped to manage?
Historians often look back at the Lizzie Halliday case as a turning point in how society processed female criminality.. While the tabloid press of the 1890s sensationalized her life—falsely linking her to figures like Jack the Ripper—the reality of her existence was far more grounded in a specific, terrifying brand of domestic predation.. Her life, which ended in an unmarked grave in 1918, stands as a grim reminder of how deeply one individual can disrupt the lives of those around them.
The impact of McNally’s crimes extended beyond the immediate victims, shaping how rural communities viewed outsiders and the perceived safety of the American farmstead.. As investigations at the time revealed, her ability to integrate into immigrant families like the McQuillans before turning on them shattered the trust that formed the bedrock of those tight-knit social circles.. Ultimately, the story of the woman from County Antrim remains a dark chapter in the annals of history, a case study in how chaos can be masked behind the veneer of a mundane marriage.
