In the Sheffield and Rotherham Independent, 22 July 1886.
Accident at Renishaw Colliery.
Patrick Sherlock residing at 20 Northgate, Eckington, met a serious accident. He was
removing props when a quantity of stone fell on him, injuring his back and crushing him.
He was conveyed home in the companys ambulence.
Presumably this was the cause of his early death in 1888.
