The vine-covered coffin had presented young Tina with an opportunity to test her hurdling skills, but it was covered in large thorns and one lodged in her leg just above her knee.
"At first, dad tried to cut it out with his pocket knife but ended up having to take me to Dr Doug Banks' surgery, where he cut out an inch-long thorn."
The upshot of her painful jump was that it flattened the undergrowth, to reveal the wooden box which, on her father's closer inspection, was found to be a coffin.
Thanks to later investigation it was revealed that the coffin housed the remains of a 1918 flu epidemic victim, who had somehow been overlooked for burial at a time when flu deaths were mounting rapidly.
Mrs Chesterfield said she believed the remains were those of a woman. Subsequently, other unburied coffins holding flu victims' remains had been located in the old, rough part of the cemetery.
The bizarre find all those years ago still popped up at times as a family talking point.
