Erdington Double Murder Coincidence

Erdington Double Murder Coincidence

On May 27, 1817, a young woman named Mary Ashford was found dead in a flooded pit in Erdington, a village outside Birmingham. She had attended a dance the night before and was last seen with a young man named Abraham Thornton. Exactly 157 years later to the day—on May 27, 1974—another young woman, Barbara Forrest (whose middle name was Mary), was found murdered in the same area of Erdington. She too had spent the evening at a place of entertainment. The man convicted of her murder was named Michael Ian Thornton. Two young women. Same date. Same place. Same victim profile. Same circumstances. And the accused in both cases shared the same surname: Thornton. The Erdington Double Murder coincidence is one of the most remarkable examples of apparent synchronicity in criminal history—a pattern so precise that it defies statistical probability. It proves nothing supernatural. It requires no paranormal explanation. But it exists nonetheless, a reminder that reality sometimes arranges itself in ways that seem designed to disturb us.

The First Murder: Mary Ashford (1817)

The original case that would echo 157 years into the future:

The Victim: Mary Ashford:

• 20 years old
• Described as attractive and well-regarded
• Working as a domestic servant
• Living in the Erdington area
• A respectable young woman of her time and place

The Evening of May 26, 1817: What happened:

• Mary attended a dance at the Tyburn House public house
• She met Abraham Thornton, a local bricklayer
• They danced together throughout the evening
• They left together around midnight
• They were seen walking toward Erdington

The Discovery: Early morning, May 27:

• Mary’s body was found in a flooded pit (marl pit)
• She had drowned, but there was evidence of violence
• Scratches and bruises indicated a struggle
• Evidence suggested sexual assault
• Her shoes and bonnet were found on the path

The Investigation: Suspicion fell immediately:

• Abraham Thornton was the last person seen with her
• He was arrested and charged with rape and murder
• Physical evidence linked him to the scene
• The community was outraged

The Trial: August 1817:

• Thornton stood trial at Warwick Assizes
• He claimed alibi witnesses who placed him elsewhere
• The jury acquitted him after deliberation
• The verdict was deeply unpopular

The Appeal by Battle: A remarkable legal footnote:

• Mary’s family appealed, demanding retrial
• Thornton invoked an ancient right: “Trial by Combat”
• He challenged his accuser to physical combat
• The medieval law had never been formally repealed
• The court had to honor his request
• Mary’s brother, too frail to fight, declined
• Thornton went free; the law was changed because of the case

The Aftermath: Thornton emigrated:

• He left England for America
• The case remained infamous
• Mary Ashford became a local legend
• Her grave marker specifically mentioned the murder

The Second Murder: Barbara Forrest (1974)

157 years later, history repeated itself:

The Victim: Barbara Forrest:

• 20 years old (same age as Mary Ashford)
• Middle name: Mary
• Working as a nurse
• Living in the Erdington area
• Described as kind and well-liked

The Evening of May 26, 1974: The parallel begins:

• Barbara went out for the evening
• She attended Doyle’s Club in nearby Birmingham
• She met a man during the evening
• She was last seen walking in the Erdington area
• She was heading home after the night out

The Discovery: May 27, 1974:

• Barbara’s body was found in the Erdington area
• She had been raped and strangled
• The body was discovered near where Mary Ashford had died
• The date was exactly 157 years after the first murder

The Investigation: Police work:

• Witnesses were interviewed
• The investigation identified a suspect
• Michael Ian Thornton was arrested
• He had been in the area that night

The Trial: Unlike 1817:

• Michael Thornton stood trial for murder
• The evidence was sufficient for conviction
• He was found guilty of murder
• He was sentenced to life imprisonment
• Justice, denied to Mary Ashford, was served for Barbara Forrest

The Connection Noticed: When journalists and researchers investigated:

• The date coincidence was immediately striking
• The shared surname “Thornton” shocked investigators
• The location match confirmed the pattern
• The victim profile alignment was complete
• The Erdington Double Murder entered criminal folklore

The Coincidences Listed

Point by point, the parallels are extraordinary:

Factor	Mary Ashford (1817)	Barbara Forrest (1974)
Date	May 27	May 27
Interval	—	157 years later
Victim age	20	20
Name connection	Mary	Middle name Mary
Location	Erdington	Erdington
Discovery location	Near water (pit)	Same area
Event before death	Dance	Nightclub
Evening out	Yes	Yes
Sexual assault	Yes	Yes
Accused surname	Thornton	Thornton
Outcome	Acquittal	Conviction

Additional Parallels Claimed (some disputed):

• Both victims were found on Whit Monday (variable date)
• Both had visited friends before the night out
• Both bodies were discovered in the early morning
• The weather was similar on both nights

Statistical Analysis

What are the odds of such a coincidence?

The Date: May 27 is one day out of 365:

• The chance of two events sharing a date: ~1/365 (0.27%)
• But events cluster around seasonal patterns
• Both occurred on what was a holiday period

The Location: Erdington is a small area:

• Crimes occur more in some areas than others
• But the specific proximity is remarkable
• The same few hundred yards twice

The Name “Mary”: Common but not universal:

• Mary was more common in 1817 than 1974
• Barbara’s middle name being Mary is a weaker connection
• But it still matches the pattern

The Name “Thornton”: The most striking element:

• Not a rare surname, but not extremely common
• Two Thorntons connected to similar crimes
• In the same location, 157 years apart
• This is statistically improbable

The Full Pattern: Combining all factors:

• The probability becomes astronomical
• Not impossible, but extraordinarily unlikely
• Coincidences do happen—this is one of the most extreme on record

Interpretations

What does this coincidence mean?

The Skeptical View: Nothing supernatural:

• Coincidences, by definition, happen
• We notice matches and ignore non-matches
• With millions of murders in history, some will echo others
• It’s remarkable but not evidence of anything beyond probability
• The human mind finds patterns where none exist

The Fatalistic View: Something deeper:

• The coincidence is too precise to be random
• There may be patterns in history we don’t understand
• The dates, names, and places aligned for a reason
• We are not privy to the forces at work

The Paranormal View: Supernatural connection:

• Mary Ashford’s unquiet spirit influenced events
• The pattern was a form of justice or completion
• Erdington is “marked” by the original crime
• Barbara’s death was cosmically connected to Mary’s

The Psychological View: Meaning-making:

• Humans need to find meaning in random events
• The coincidence was publicized because it was striking
• Uncounted non-matching cases go unreported
• We created the significance retroactively

The Victims Beyond the Coincidence

The pattern should not overshadow two real human beings:

Mary Ashford: More than a data point:

• A young woman with hopes and plans
• Killed before her life could fully unfold
• Denied justice when her killer was acquitted
• Her grave in Sutton Coldfield reads: “As a warning to female virtue”
• She deserved better than to be remembered primarily for dying

Barbara Forrest: A nurse who cared for others:

• A young woman serving her community
• Killed while returning from an innocent evening out
• Her killer was convicted, unlike Mary’s
• She deserves to be remembered for her life, not just her death
• The coincidence should not obscure the tragedy

Legacy

The case continues to fascinate:

Criminal History: The Erdington murders feature in:

• Books on coincidence and probability
• Criminal studies courses
• Documentaries about unlikely events
• Discussions of pattern and meaning

Local Memory: In Erdington:

• The cases are part of local lore
• Some residents know the history well
• The locations are marked by memory if not monuments
• May 27 carries weight

Philosophical Questions: The case raises issues about:

• The nature of coincidence
• Whether patterns have meaning
• How we process improbable events
• The limits of statistical reasoning

No Paranormal Explanation Required: And yet:

• The coincidence exists
• It happened
• No explanation diminishes its strangeness
• It stands as one of reality’s most improbable alignments

May 27

May 27 comes every year. The date marks Whit Monday in some years, falls in the warmth of late spring, brings people out for the evening in Birmingham and Erdington as it does everywhere. Most years, nothing remarkable happens on May 27 in Erdington. Young women go out dancing and return home safely. Men named Thornton live ordinary lives.

But twice—only twice, but twice exactly—the day aligned with horror. A young woman named Mary. A place called Erdington. A man named Thornton. Rape and murder and a body found in the morning.

157 years is a long time. Generations lived and died between Mary Ashford and Barbara Forrest. The world changed beyond recognition. And yet, somehow, on one day in 1974, time folded back on itself. The pattern repeated. The names matched. The place held its curse.

Call it coincidence. Mathematically, that’s what it is—an improbable but not impossible alignment of factors that happen to create a striking pattern. The universe doesn’t care about patterns. Events don’t know they’re echoing each other. Mary Ashford and Barbara Forrest never met, never could have met, shared nothing but the terrible manner of their deaths and the strange symmetry of the details.

But knowing it’s coincidence doesn’t make it less unsettling. Knowing the statistics doesn’t explain why these specific factors, these specific deaths, these specific names. The Erdington Double Murder coincidence doesn’t prove anything supernatural. It doesn’t need to. It’s disturbing enough as it is.

May 27 will come again next year. And the year after. Probably nothing will happen in Erdington. Probably the pattern has exhausted itself.

Probably.
